I can understand why you just shrug your shoulders about the matter, and that is OK. It probably is a good thing that you are complacent on the issue. However, homosexuality is not benign, and those who engage in it don't keep it in the bedroom - it ends up constantly being shoved in the public's face.
Granted all kinds of sexual perversion is now being mainstreamed in the media and in the schools, but it doesn't mean that good people should give up the fight when it becomes clear that this is a raging culture war.
