Well, according to Levitical law God hates a lot of other things, as other people have pointed out. A literal reading of Leviticus doesn't work, because again, Christians aren't following those rules.

As Stephen points out, Jesus' exception may be a later textual variation to deal with pastoral realities. Of course, that's not a view than an evangelical can commit to, or at least not the sort of evangelical that I was. But oddly, many evangelicals are prepared to accept the re-marriage of people who don't meet the exceptions, and yet disapprove of homosexuality. I'm not the only one to point out the hypocrisy here.
