If that were true we could never understand Shakespeare, for whom certain words had different meanings than they have today. We don't seem to have any trouble in understanding texts that are even older, although the meanings of words have changed in the interim.
Excuse me, but that is bullshit. Most people, I would bet well above 95% in America, would have a terrible time parsing Shakespearian sentences. I consider my language skills to be fair to middling, which is to say, far and away superior to that of the average man whose skills are all but nonexistent, and even I still have some trouble with certain passages. Moreover, I have noticed in myself and have suspected it in others that many of Shakespeare's expressions offer only a general sense of their fuller and more detailed meanings. I know what he is saying and often get a sense of the profundity of his precise meaning. Nevertheless, I am pretty certain that there are subtleties that I am missing.
Language changes constantly.
Not all language changes constantly, but more importantly it is not change that matters so much as the sort of change.
"Assassin" meant a hashish-eater.
It is actually the plural form of "hashish user", but its actual applicable meaning is precisely that which it is today. The hashishiyyin were a Muslim sect who would, well... asssassinate rivals after consuming hashish. The relevant meaning was that of assassins. The eating/using hashish part was just the device for uniquely identifying and distinguishing them from others. Therefore, the fundamental and "inner" meaning of the term has, in fact, not changed a bit since the 13th or 14th century.
"Awful" meant wonder-inspiring.
That is correct, and the current vernacular usage is not right. Now, taking that example and reading a text from, oh, say the Victorian period where the author describes an "awful sight", is would be very easy for the reader to conclude that the vision was of necessity terrible, when in fact it may have been something very different.
I used to design programming languages and write compilers - taught compiler construction - and one of the cardinal rules is that keywords never alter their meanings. There is strong reason for this - the machine is stupid and if you tell it the wrong thing by using a keyword incorrectly, the machine will DO the wrong thing. In the military, certain organizations have developed very specific communications languages such that miscommunication becomes a very difficult thing.
"Fun" meant to cheat or hoax
.
That was originally the VERB form of the word, not the noun.
"Bully" meant a good person, or a darling.
That is right. Teddy Roosevelt is often portrayed as saying "bully" when he was pleased with something. And with this you once again make my point. Bully derived from the Dutch "boel" - "lover". Through the 17c it morphed into a "good man" and then one who is essentially a loudmouth, and finally to one who picks on the weak. So if I have no knowledge of the etymological origins of the word and read a book from 1470 and it tells of the bully whom "he held in the highest esteem", I might be lead to infer that this guy was mentally impaired in some significant manner, to be in love with an abuser.
"Nice" meant foolish or silly. How has the change in these and other words impeded our understanding of history?
I cannot, off the top of my head, say how those particular words may have altered our understanding of historical texts. I can, however, say that such alterations have indeed caused endless trouble for many people. The understanding of religious texts is a prime example. I knew a man who nearly became my father in law. He had been an ordained Jesuit and an enormously erudite man, specializing in ancient languages including Aramaic, Hebrew, Latin, and Greek. His PhD thesis was a new translation and analysis of the New Testament wherein he demonstrated the manifold problems of determining the proper semantic content of the various passages. This was the man who first taught me to appreciate language and demonstrated to me how delicate the semantics of words and sentences can be.
You mean that mindless prejudice against gays might disappear? And you think that's a bad thing because irrational bigotry is a valid social order?
Those are YOUR words, not mine. Perhaps this is a reflection of your own positions. It has absolutely nothing to do with mine. But if an individual chooses to be bigoted, that is his business and nobody holds any authority to force him to think/feel otherwise.
Given your visceral loathing of gays (your rhetoric betrays you), I can see why you would find it unacceptable to treat them the same as straights when it comes to a legally-recognized union.
You don't know shit about me, pal. I don't even loathe people such as yourself who make assumptions based on an apparent lack of analytic skill and very bad transactional habits. To wit: had your habits been up to snuff, you would have asked whether I loathe homos prior to making your weakly founded accusations.
If you want to dance, for God's sake learn how before getting on the floor.
It's more normal than you would like to think.
Since you have no idea what I think, but base your opinion on a very superficial parse of my expressions, I'd have to say you're talking our your other end.
What proof do you have that they choose to be gay? Can you positively rule out a genetic factor?
Firstly, I have several queer friends some of whom I have known more than 40 years. I've had dozens of queer acquaintances. Many say they "knew" by the time they were in 6th grade that they had no interest in girls, but a very substantial proportion - just guessing here @ ca. 20-25% - told me in no uncertain terms that they chose to be gay or were directed to that lifestyle by third parties.
All that aside, they still choose to be gay, just as I chose to be straight. I could VERY easily have chosen the queer lifestyle. I grew up in a place where rape and physical beatings were a daily reality for children. I've watched kids only a year or two younger than myself curled up in fetal balls in a corner, twitching after being gang-raped by other students and even teachers. I had all the opportunity in the world to go full-queer and it would have been easy for me in terms of environmental support. But I had no interest in it and CHOSE to be what I am as the matter of nature. I assume that gay people do the same, but it is still a choice. They can and often DO choose to lead the straight lifestyle, even today. They might be miserable in it - I cannot speak for them - but they most definitely can make that choice. So yeah, it is most definitely a choice. We are men, not amoebae. We think and act pursuant to those thoughts; we do not merely react to stimuli in deterministic ways.
The fact that you got all bent out of shape by some guy who hit on you indicates that you're the one who's insecure and who has to express how macho you were.
If that is what you took from what I wrote, then you have a terrible problem with reading comprehension. I've been "hit on" by more men than you could shake your foreshortened stick at and on many occasions I have been so very flattered by it. In fact, several of my wife's colleagues are in love with me. The instance in question, first of all, was not one of being hit on. It was one of a complete stranger in a speedo attempting to hump my bare leg (it was August and I was in shorts) and I was not interested. I politely told him to stop and he refused to respect my wishes. I told him once again and he still advanced upon me. That was when I became more forceful. If you think he had the right to rub his uninvited weenie on my knee, then you lack all credibility. I simply asserted my right to travel unmolested by a stranger who, like a dog in the mood, decided mine was as good a post to hump as any. That you took anything else away from what I wrote shows you have a problem of some sort.
You have a very strange and warped concept of freedom. Apparently yours is nowhere near "live and let live".
And you appear to have a terrible comprehension deficit. You have my sympathy and that is no sarcasm.
