I may not have expressed my point well. I don't disagree that homosexuality is nearly "universally" condemned in religion - that does not translate into a valid compelling interest in secular law.
As far as inter-racial relationships, "love others as you wish others to love you" and "treat others as you wish to be treated" give your statement the lie.
Could you explain to me how this applies only to differences in race, but not to religion or sexual orientation?
Racial differences are benign bodily characteristics that have nothing to do with behavior. A person is unable to change his race (Michael Jackson notwithstanding!). It is neutral. To hate someone because of his race is wrong, although not a punishable act because it is thought only. But to discriminate against a class of people because of their race is criminal because all people of a certain race are not alike, it is not a behavior, and it is not chosen. This is obvious and you know it as well as I do.
Sexual behavior is completely different: it is behavior, it is chosen (as is all behavior) and therefore it can be stopped or started - or changed, and it is not neutral. There is a vast amount of information on the deleterious effects of homosexual behavior on individuals, and society as a whole. I have read it here on FR and if you haven't seen it you haven't looked.
Considering religion, that is also chosen - but it is consciousness, not necessarily behavior, although differing behaviors are associated with various religions (attending religious services on certain days, etc). To hate someone because of their religion is also wrong, but is not a crime unless people are suppressed or otherwise harmed because of their religion (for instance, the Nazi treatment of Jews). If members of a religion perform acts that they claim are their religious duty (such as killing Americans in the name of Jihad) then such acts leave the realm of religion and enter into the realm of criminal acts or acts of war, and then are treated as such.
Additionally, love doesn't necessarily mean that all behaviors are loved. When you love someone it doesn't necessarily mean you approve of everything that person does.
I have tried to reply to your comments seriously, although your comments seemed not to warrant such weight. But there are others reading these back and forths.
