Studies show that Non-Protestant Christians are much more likely to support same-sex unions than Protestants; 63% of African Americans claim that they are Baptist or Protestant, whereas only 30% of white Americans are. Religion, as measured by individuals' religious affiliations, behaviors, and beliefs, has a lot of influence in structuring same-sex union attitudes and consistently influences opinions about homosexuality. The most liberal attitudes are generally reflected by Jews, liberal Protestants, and people who are not affiliated with religion. This is because many of their religious traditions have not "systematically condemned homosexual behaviors" in recent years. Moderate and tolerant attitudes are generally reflected by Catholics and moderate Protestants. And lastly, the most conservative views are held by Evangelical Protestants. Moreover, it is a tendency for one to be less tolerant of homosexuality if their social network is strongly tied to a religious congregation. Organized religion, especially Protestant and Baptist affiliations, espouse conservative views which traditionally denounce same-sex unions. Therefore, these congregations are more likely to hear messages of this nature. Polls have also indicated that the amount and level of personal contact that individuals have with homosexual individuals and traditional morality affects attitudes of same-sex marriage and homosexuality.
