I saw one who opposes this saying 'this opens the door for legalisation of incest yadda yadda' - basically saying it's a slippery slope. His argument was that this ruling basically would allow anything between consenting adults.
One of the church leaders argued that the ruling would make the country less moral and that 'right' and 'wrong' now no longer were concepts used in US courts.
Both go too far I think. Whatever you do with your partner in bed is your own thing. I sure as hell don't find homosexual sex appealing (not even amongst women) but it's not my perogative to tell others what to do in their bedroom.
OTOH, in the US there are lots of bedroom laws. I had a list before - in some states only certain positions were legal etc. So they aren't realyl enforced - or rather, they weren't until that much published episode where a jealous lover called to say someone was being attacked at his ex boyfriends place and the cops busted in and found two mens having sex. Heh. The two were prosecuted which I think lead to gay right activists getting in the spotlight and managing to push the case to the Supreme Court. Seems those that wanted to prevent it sort of screwed it up.
So, if the gay right people wanted EQUAL rights, then they should go fight those laws who target and opress heterosexual couples as well! Failing to do so would leave the gay people with more rights, and...that ain't...equal...
Anyway. So two dudes or girls have anal sex. Anatomically speaking, there's very little difference between the anus of a man and the anus of a woman. Which of course leads to some disturbing conclusions I won't bring up
.
Will only say that from an objective, technical point of view, it's just as 'unnatural' (one argument against) for a heterosexual couple to have anal sex as it is for a homosexual couple. So, either it's allowed for both or for none - can't ahve double standards.
