"Dumb"? Is it that serious?
But anyway, since the pair of you are clearly smarter than I am, given the confidence in your statements, why don't one of you tell me what the 'correct' statistics are, and furthermore, one of you might care to tell me how you came to such conclusions? Are you scientific professionals who have conducted in-depth case studies analysing non-heterosexuality in human beings in order to source what you feel may be the 'correct' numbers?
I don't think it is naive or unwise to presume that most people on the planet are heterosexual, but then again this is LPSG, where we generally come here to look at photos of attractive males and view videos of amateur or professional pornography, so of course the element of "wishful thinking" will be present. Hey, I wish most "hot guys" were 'not straight'/into other men, as well, but I also wish I could sprout a pair of fluffy wings out of my back and achieve flight. Maybe I was hasty throwing out those numbers (I was being more 'sarcastic' than 'literal') but I also don't believe homosexuality (including bisexuality) is as common as people nowadays might want to mislead people into thinking it is, either to fulfill their own erotic fantasies or for other selfish desires in the context of political agenda.
I have never seen any or even heard rumours of any existing. If I had seen or heard of any, I would have posted them here on LPSG or tracked them down in order to bring them here, respectively.
