You're painting with an awfully broad brush there Drew. Every board, since the dawn of BBS's, has had its spectrum of posters. This forum is no different; though I do think this forum has a better signal-to-noise ratio than most.
The same brush is used here though.
Someone posted something about nuclear bombs or star wars rays and linked it to the whole truth movement. I have never heard of that "theory" before.
By the same token, I could link all that agree with the official story as racist because someone from their "group" made numerous racist comments.
I just got called a nutter because I "appear" to be going against the majority here.
The same thing happened when I went to a government involved conspiracy theory forum and went against their actions towards personal attacks.
