OMG, are you that fricken stupid? you want the government to force its citizens to accept homosexuality and gay marriage as normal human conditions. you want to tell pre-pubescent teens that they can go either way or both ways and its just hunky dorry. you want to deny mammalian biology and encourage male/male and female/female sexual relations.
and lets be truthful, this is all about sex and who you do it with. mammalian homosexuality is not normal, its an aberation. you say you can't help it, and I accept that. but your genes are screwed up, you have a genetic abnormality, just like someone with MS has an abnormality.
The fact of human sexuality is that 99% of sexual activity between two humans is done for non-reproductive purposes.
It is normal for humans to have sex that is not intended for reproduction.
Humans cannot be compared to all other mammals for the purpose of establishing what is 'normal'.
'Normal' sex for dogs, for example, is to copulate over a short span of a few days, every 6 months or so. How does that in any way belong in any measure of what is 'normal' for humans?
sure, dog sex is different from human sex, wow, I bet no one but you knew that.

what you don't see is two male or two female dogs copulating.
So what? I've just proven that comparing humans to other animals is not a valid comparison, so it doesn't matter what dogs do normally.
How often do you see dogs using contraceptives?
we spey and neuter dogs, do you recommend that for humans?
humans are mammals with large brains, other that brain size we are no different from dogs, chimps, dolphins, lions, or elephants. Our biological reproductive sex organs are designed for one purpose only, to reproduce our species. Because of our larger brains we also use our sex organs for pleasure and fun. But biology cannot be ignored, the human rectum was not designed to be penetrated by a penis, the vagina was designed for that purpose (and it works very well). Same sex bonding and friendship is normal and good for everyone involved. Same sex sexual activity is an aberation and is damaging to society.
Anyone who claims that a little boy raised by two lesbians will grow up with normal male feelings is fooling themselves, same for a little girl raised by two gay men.
