*this is not a blanket statement on all Christians. This mostly applies to evengelicals as they are the leaders in Christian politics in America.
Christians in America fight to make abortion illegal and at the least discriminate against LGBT, at worst make LGBT lifestyles illegal. Both of these arguments are supported by religious beliefs. Why aren't these same groups attempting to allow discrimination against those who have premarital sex, or those who use birth control (not I'm not saying arguing against providing birth control as they already do that, looking at you hobby lobby.) Or to make tattoos illegal, or to discriminate against those who have tattoos illegal. In the tattoos case even the argument that this is from the old testament is inconsistent as the passages against homosexuality are exclusive to the old testament.
Is this evidence of inconsistencies? Is this evidence that Christians are just prejudiced against certain groups but use religion as an excuse for that prejudice?
