Being gay:
on an evolutionary stand point it serves no logical purpose.
There was a study suggesting that there may be an evolutionary advantage to having gay males in one's clan. A clan could use a few people who do not have families of their own, so they are effectively "extra labor" that can help the other people in the clan with families. I confess I don't remember this study all that well, but I definitely think that primitive societies need some fabulous people to help with interior decoration and musicals.
Who invented family anyway? You get stuck with just one woman, when your urge is to spread your seed amongst a wide sampling of beauties. If you get divorced (because she's found out about your seeding activities), the wife gets half your stuff. You can't go fishing and hunting any time you want. Your kids turn into weirdos for six years before you send them off to college. You get to pay for tuition, when that money could go into guns and ammo instead. When you get old, they tell you what to do.
I personally believe that love is love. You want to be gay? be as gay as you want, you want to be straight, be as straight as you want, but please don't trample on another persons choice as to who they want to date. Your relationship doesn't effect them, so theirs shouldn't effect you.
This!
