Why not?
I believe Christ said that loving thy neighbor (along with honoring God) were the two most important commandments. Notice he didn't say love thy straight neighbor, but love thy neighbor...irregardless.
And it's not like Christ set the best example for how to live purely hetero lifestyle (considering he wasn't married and he hung around with a bunch of other guys).
"What's love got to do, got to do with it?" Good song, and apropos. The behavior is forbidden by the Lord, as is other sexual behavior outside his laws regarding sexual expression between his children. Please don't take the tired, old, worn out treadmill and say that because we oppose homosexual conduct we hate homosexuals.
Your second comment has some serious problems in that we don't know anything regarding Jesus' marital status in mortality, and the fact that all the Apostles were male implies precisely what to your mind?
