So many Christians seem to feel that because of some esoteric passages in the bible (which can be interpreted many different ways) it is acceptable to treat gay people like second class citizens. There are also passages in the bible stating that you should not charge a poor man interest (Exodus 22:25), so why aren't these Christians upset about certain banking practices? Do they just pick and choose which causes they are going to be fervent about? Do they hide behind their religion so they don't have to admit that they are just bigots? This is not directed towards all Christians, just the ones who are so zealous when it comes to demeaning gay people.
