Truthers are dumb, I don't think saying "we should get more details" about one of the most significant events in our history makes someone a truther, but I don't know all the details about his positions on this. He doesn't seem to be a truther, Jesse Ventura is a truther, their speech is very different. Then again, he might be.
Regardless of that, his foreign policy positions are actually far more sane than people give him credit for. He is against stomping around the globe as an imperial force, which resonates with a lot of people who are sick of America trying to police the whole damn planet.
He has strict liberarian positions on issues of personal freedoms and stuff like prositution and drug use. These are controversial opinions that do not jive well with social conservatives, but he stands by his positions with a convinction that few politicians have.
I respect Ron Paul for being in the US congress for so many years and remaining one of the most principled people in the entire government. Many times he is the sole person voting one way on a bill while literally every other person votes for it. Just because he's doing something different doesn't make him right, but this does show that he stands by his principles rather than caving into the washington establishment.
I have very many serious disagreements with Paul, and I would not vote for him, but I also see the sanity in some of his positions and criticisms of the status quo.
He can seem a little nutty at times, but the problem is that Washington is so far up it's own ass with everyone in office being as crooked as a dog's hind leg. When everyone in Washington is totally disconnected from reality and wrapped up in supporting special interest groups, anyone who throws a little bit of Truth into the debate is going to be ostracized as being "crazy". This doesn't mean that everything labeled crazy is true, but more often than not Truth is labeled as crazy by the establishment.
Paul displays real honesty, even when he's saying something extremely controversial, because he believes in it. I highly respect that. His principles come before politics, and every politician makes this claim but their actions speak louder than words.
He does not tow the party line at all, and frequently stands up to members of his own party, something that is rare amongst Democrats or Republicans.
One of the strongest areas I disagree with him is economics, and I am not a libertarian by any stretch, but I can see Paul as being an honest libertarian and not just a Republican who throws on the label to appeal to people.
