For many people, the world will end depending on the outcome of this election cycle. If you mean it more literally, that the world is literally going to end depending on the election outcome, it is a pretty safe bet we will have already been a group that got the axe... quite possibly literally.
Maybe it is an unpopular position here, but when the lesser X will prevent the death of 1,000's of lives, the destruction of countries both by war and the ensuing flight from war, the incarceration of numerous more innocent lives, and as a cherry on top, will reduce tax and regulatory burden, I will gladly accept.
A government doing less harm is good. Taking the steps to ensure your government will do the least harm, is good.
Why do you value higher voting on principle over the death of 1,000's of lives, the destruction of countries both by war and the ensuing flight from war, the incarceration of numerous more innocent lives? Or is that not a consideration for you? It is just principled or not... you don't even look to see what the different outcomes would be?
I agree with you to a point about 'holding out your vote'. A couple percentage points tax decrease or a few regulations doesn't necessarily warrant caving. But when we are talking about lives? and 1000's of lives at that?
I'm sure your familiar with the golden rule, what would your wishes be if a foreign government was ravaging your land causing death and destruction with war, and the voters of that foreign government had a candidate with a path to victory that intended to end to the warfare? Would you hope that they would vote for him?
And didn't Castle say that he'd leave at the Gitmo prisoners in prison forever, because they had been in there to long? Does that principle extend to individual's held in domestic prisons? Is it a principle at all? Is it consistent?
You're putting it as a variant to the trolley problem. Passively allow the
greater evil to speed down its path towards thousands of deaths and all kinds of misery, or actively cast a vote for the
lesser evil to change the path into some lesser infringements of another group of innocent people. Ultimately, when are the consequences so sever our principles must be sacrificed? Yes, taken to the
very extreme, I and probably most libertarians agree such conditions can exist. It would be dishonest to say anything else. Inversely, there's no point in rejecting a candidate for the tiniest of flaw or deviation from what we percieve as a 100% non-aggresing stance.
With that said, are the consequences involved here remotely close to justify abandoning the principles? Is Johnson/Weld all one could realisticly hope for, with just a few flaws? No. I too feel the horror of all the misery that American interventonism has created. My country is under enormous strain from the burden put upon us by the huge inflow of migrants and refugees, and I have no problems imagine what sufferings the middle east is having. I would most certainly wish for anything or anyone that would ease the conflict as soon as possible if I'd be unfortunate enough to having been born into the region. Taken at face value, i do believe most people intuitively wants to save lives when put against some theoretical principles, the same way people wants to pragmatically save the 10 lives in the trolley problem than just 1 life and a principaled set of ethics. Let's be clear about what's at stake here though. The actual comparision isn't a thousand lives against lofty ideals and theoretical principles. It's thousands of lives now stacked against an unmeasurable more lives lost in the future.
What created this situation we have now to begin with? The disregard for those principles of self-ownership and individual liberty. Until those principles of freedom reigns, we will have war in one way or another and people will die or have their lives restricted. From direct violence to indirect economic suboptimal growth. The sacrifices of the outcome of this election cycle most probably will bring, yet how terrible they are, quickly diminishes when compared to the misery of all the coming election cycles where individual liberty still is a non-issue. The only relevant question must in the end be, do Johnson sway people into our philosophy of freedom? I don't think he is. Johnson is a symptom reliever, but he's not advancing any cure to the root causes. At the very essence of his campaign is the notion that your country can't be run on those principles, that they don't mean much to him at all and therefore shouldn't do to those he's pandering to. That's the message him constantly violating these principles sends. Johnson wakes up a sentiment of non-aggression already present in most people but he isn't swaying them to make it a principle to apply consistently making infringements of peoples rights still left to the arbitrary popularity of the present day for such actions.
When Johnson thinks it's morally justifiable to send armed men to combat people who won't bake cakes
domestically, what says he one day can't apply the same justifications to send armed men to combat people
abroad who are doing much worse things than merely withholding gay people their private services? From a libertarian perspective I see little moral difference. Sure, international wars are unpopular, and rightly so, but if that changes someone like Johnson has little ground to argue why it's wrong with no principles to fall back on, and i'm not sure he will even attempt it. Because that's what I feel the Johnson/Weld campaign is constantly signaling - "Hey, we want to extend the rights in areas we like, such as weed and LGBT, but we're much more reluctant to do the same to people we're not fans of - religious people, gun owners, smokers and so on." That's not a liberty message, that's merely self-interest and putting oneself above others in the rights department.
Could he still act as a 'gateway drug' to a principled liberty movement? Maybe, but not through himself or his campaign. Instead,
we could use him. His campaign is sure to expose a lot of moderates to our views, and we can use it to further our causes, absolutely. But that depends on us supporting our cause, not Johnsons, having an active, viable movement - which takes all our efforts, resources and support aimed our own way. The last thing we should do then is to cave in to support a lesser evil. Just compare how the ancap community feeds off the broader influx to the libertarian camp, while still championing their own ideals.
Johnson for moderates, libertarians for libertarians.
