Are there any reasons why two people in love shouldn't be allowed to get married except for Christian Old Testament and other religious, including Muslim, objections?

After an initial resistance to the thought, for no good reason I can imagine, I can't think of any. But there may be.

Biological male and biological female are rather blurred lines, anyway. There are folks with chromosomes all over the map, and should they be without civil rights?

Another factor is that they may as well have the same opportunity to be miserable as the rest of us. It's an equal opportunity world. :-) (That was supposed to be humorous.)

(As an aside, I'm convinced homosexuality is 98-100% genetic. Would someone like Turin, for example, have committed suicide if he could have chosen his sexual orientation?)
