What does deviant sexual behavior have to do with marriage?
What does any sexual behavior have to do with marriage?
Maybe it's just me, with my conservative traditions and all, but I was raised to believe that marriage was a committed union between two people, that the most wholesome marriages were based upon love and dedication, and that married sex was a celebration of that love -- the bonus, not the purpose.
To define gay people entirely based upon the sex that they have also reduces straight people to the sex that they have. This is frankly more than most of us want to know about each other.
Saty's comment to you may have seemed rude, and of course it is, but it is absolutely no different from the argument you are making.
By reducing gay people's lifelong commitments to the sex they have, you also reduce your own marriage to the type of sex you have with your spouse. If you are offended by hearing your wife talked about in these terms, then you should realize how offensive it is to gay people to hear themselves described the same way.
Also, it should be said that you loose your argument when you bring in the phrase "deviant sexual behavior", for two reasons. One, as others have pointed out, there is nothing deviant about homosexual sex. In addition to that, putting "deviant" before sex just makes it sound like more fun. So when you ask "What does deviant sexual behavior have to do with marriage?", most people are going to think "It depends how fun the marriage is!"
Just saying.
