== they don't know what causes this? == 

 that's embarrassing. i thought i'd finally look it up and etc etc. unbelievable. then again, they can't - or claim they can't - get a handle on the common fucking cold, so i guess this kinda thing is even more difficult. but science; what a joke. we're just paddling around with a different set of problems than the ones plaguing us when it began to get off the ground, whenever that was. no progress, only superficial change. new wallpaper. so what do i tell my kid when he asks me where gays come from? thanks a lot, brainiacs.
