What do you believe that most people on this site don't?
I'm especially looking for things that you wouldn't even mention if someone wasn't explicitly asking for them. Stuff you're not even comfortable writing under your own name. Making a one-shot account here is very easy, go ahead and do that if you don't want to tarnish your image.
I think a big problem with a "community" dedicated to being less wrong is that it will make people more concerned about APPEARING less wrong. The biggest part of my intellectual journey so far has been the acquisition of new and startling knowledge, and that knowledge doesn't seem likely to turn up here in the conditions that currently exist.
So please, tell me the crazy things you're otherwise afraid to say. I want to know them, because they might be true.
From your other comments, I believe you're confusing "I don't believe men who say they are bisexual" with "I don't believe men can be bisexual."
It's clear to me that, in American society at least, the majority of bisexual men are to be found among the ranks of men who would never identify as anything but straight, sometimes even to the men they have sex with(!). Conversely, many of the men that DO identify as bisexual are merely finding a graceful way to transition to a homosexual love life.
Thus, that a man who identifies as bisexual is mostly likely gay may be true (though I doubt it--especially among men who have been out as bisexual for more than, say, 5 years) is not an indication that male bisexuality doesn't exist--only that self-professed bisexuality is scantily coterminous with a bisexual orientation in males.
Being wrong in the way that you are wrong will probably not damage the accuracy of your insight when conversing with individuals about their sexuality (you'll correctly assign a high probability to his being gay if he says he's bisexual), but it probably WILL damage that accuracy when analyzing human populations in the abstract (you'll incorrectly assign a low probability to the existence of large ranks of males who engage in and enjoy sexual relations with both men and women).
As I've said elsewhere, possibly even on this thread... if my culture makes it more difficult for men to identify as queer than as straight, then even if sexual orientation varies (like many other things) continuously within the population, I should expect the majority of more-than-negligably male-oriented men to identify as straight.
