>>12950081there are many supporting facts, such as the study of brain component size in straight males vs straight females and how homosexual individuals often have brain component size ratios of the opposite sex.
there is also the very observable fact that basically all mammals have homosexual individuals at roughly the same rates: 1/4 of a given species are a little gay and maybe 5% of them are totally gay.
whatever gayness is, it's probably at least 50 million years old.
