a couple things:
first, michjackass has mimicked posting styles of multiple posters since he began posting on the boards. nothing new here, moving along . . .
more importantly, it may not be "scientifically proven" homosexuals are born gay and, i'll admit, up until speaking to the parent of a set of identical twins about their children's sexuality (these twins are now in their mid to upper 20's), I agreed with greed: however, what the parent had to say totally changed my view and belief.
the parent told me their twin daughters, at an early age (2 to 3 years) displayed very different styles. they played with different toys, one daughter playing with girly toys (i.e. barbies/dolls/etc) and the other always wanting boy toys (matchbox cars/trucks, race tracks, toy guns, etc.) to play with. one little girl always liked dressing up in dresses, the other little girl threw a fit every time the mother would try to put one on her for church or other events. she said she ended up ditching all the dresses/skirts/etc. for that daughter and allowing her to wear pants to church and other social events. even colors were an issue with the first little girl liking her clothes to be typical girly pink/purple/pastels/etc. and the other little girl wanting nothing to do with such colors.
ultimately, the parent had the girls DNA checked and found just what rifle has indicated above: the X chromosome of the children's DNA were exact mirror images of each other, i.e. the X chromosomes were opposite, while all other components of the children's DNA are exactly identical.
today, the first daughter is married with children and the other is a lesbian.
does this prove scientifically that homosexuals are born that way? perhaps not, but it sure as hell changed my view on the matter.
one other example: a guy I graduated high school with has 12 year old twin sons and I had them on my little league football team 2 years ago. one absolutely loved knocking the shit out of whoever we'd put across from him. wanted to try playing every position on the team. the other made it known he wanted nothing to do with the game and that he'd rather be on the sideline cheering and told me the only reason he was playing was because he and his brother made a pact they'd do all such activities together, and that his brother agreed he would join the color guard and join gymnastics with him (not saying heteros can't be members of the color guard nor gymnasts, but hopefully you get the point). the one was always talking about "bitches" and what he'd like to do to them (yes, at 12 years old. these 2 little shits are, without a doubt, the most foul mouthed kids under the age of 18 I've ever been around); the other would yell, "ewww, gross" when his brother talked about "tits, pussy, and ass" (fwiw, I did try correct them, but when their dad laughed things they would say off, what the hell could I do?).
anyhow, the one acts quite feminine. while the parents haven't had their DNA checked, it wouldn't surprise me in the least if theirs was exactly like the example I gave above. and, while neither has come out and professed their sexuality, it won't surprise me a bit when the one comes out and says he's gay.
