Whatever your position on the host of "fringe" topics or issues is, try to make your argument as complete and concise and rational as possible but most importantly make it in a way that doesn't hurt Ron Paul.
I have spoken at length about the legalization of drugs to people you would NEVER in a million years think would eventually agree with me and they did. I have likewise made my position clear to gung ho kill'em all and let God sort'em out types about the policy of non interventionism and armed neutrality and guess what? I convinced them. I have also made my case for suspicion of government relative to the 911 truth issue. I didn't come across as some crazy guy who was accusing my own government of flying planes into buildings and deliberately murdering innocent Americans. I made them THINK and in so doing accomplished plenty. It's all in HOW you present yourself but I will say this. Though I have a lot of questions about what happened on 911 and at one point was almost convinced that people in our own government were behind it I realized how crazy the majority of Americans think that position is and I backed off mainly because they knew I am a Ron Paul supporter and the last thing that I want to do is hurt the cause and the loud outspoken "911 was an inside job" buddies of mine are the ones who the media focuses on not me the guy who strategically says "there are still a lot of questions that patriotic, intelligent Americans still have and in my view of American history it always has been from our very beginning the most American thing we could ever do and that is question our government and to be suspicious of government. In fact, our entire country was founded on just that". No one can deny that is true and then to be patriotic they too might look into the government's official story without the rose colored glasses of trust and belief.
When I'm talking about legalization of drugs to "conservatives" or Republicans I always point out that it wasn't until progressive authoritarian Democrats that drugs and alcohol because illegal and that was the first time our Federal Government presumed to tell free people what they could ot could not put into their own bodies and unless we're free over those choices we're not free at all. Its Democrats who want to control everything and pro choicers who attempt to take every possible choice that we can make for ourselves and out it into the hands of government to make for us. That it's not a conservative issue at all but liberal control freaks do all these things like drug laws, cookie laws, trans fats laws and anti smoking laws. I also remind them of the unintended consequences of Democrat authoritarianism like the crime culture the war on alcohol and drugs resulted in like our dependence on oil, Al Capone, and the gangs and cartels, all the associated killings and loss of our liberties along with the financial costs in a police state environment.
One of the most difficult things that I have encountered is to try to convince Republican neocons that the Federal Reserve is a greater threat to our liberties than Islamic terrorists. Thats for another post.
