Unfortunately, this is what passes for "conservative" in the Catholic Church. It does little good to oppose homosexuality if one buys into the evolutionism and higher criticism that feeds it and other things like it.
For one thing you're gonna have to define "higher criticism" for us.
For another, we don't know what you're talking about with evolution -- are you a creationist? Do you think there's a conflict between the religious truths communicated in Genesis and the scientific facts that contribute to evolutionary theory?
Regarding conservatism, I agree it is tragically ironic that when Cardinal Law was being attacked for being too heavy-handed and conservative it turns out his problem was not being hard-nosed ENOUGH.
