Ake, it strikes me that for someone who doesn't trust/like "such facts", you don't bother to back up your claim that "a huge majority" of the world's population is virulently against homosexuality. I haven't seen you cite any statistics at all, and yet you're trying to use the power of nebulous and unverified numbers as a respectable argument.
The Kinsey studies, on the other hand, are well-documented and well-researched, and have been verified by independent sources (as Don pointed out).
And of course, statistics aside, it's also true that societies evolve and change over time. I mean, a few hundred years ago the thought of black people or women voting (gasp! the horror!) was a much more universally contested issue than gay marriage is today. And yet, the thought of denying women or black people the vote today is unthinkable to most of us (with apologies to any Miami-Dade voting officials who may read this, of course *wickedgrin*). The point is, giving the vote to women and black people didn't automatically cause universal acceptance; as I pointed out earlier, that's hardly the goal. People deserve the same rights, whether Joe Sixpack (not to mention Pat Robertson) approves or disapproves.
I don't for a single moment believe any of this will change your mind, of course. We can put forth a reasoned argument, and you can dismiss the "facts" and then turn around and accuse the lot of us of irrationality until we are both blue in the face. But as they say, it's better to light a candle than curse the darkness, eh?
