Christian culture members by and large identify themselves as Republicans. The importance of doing this seems to be on par with believing Jesus died on the cross for your sins.
If you are raised in Christian culture or entering it as a “new believer,” you are almost invariably taught that the left wing is God’s opposition. The Bible doesn’t mandate this; Christian culture does. You will infer that the ACLU is bad and Rush Limbaugh is good. Reagan & Bush: yes. Bill Clinton & Jimmy Carter: NO. Hillary Clinton: HELL no! Obama: NOBAMA. Universal health care is ridiculous. Clarence Thomas was telling the truth. Anita Hill was lying. Capitalism is the way God intended. Gay marriage will destroy the institution and the next thing you know animals will be getting married. Ann Coulter is a hero. Richard Dawkins is a threat. And on it goes.
When you are raised in any school of thought it is extremely difficult to challenge it. Venturing into virgin territory is uncomfortable for anyone. Some people feel they may face estrangement from the Christian community if they question conservatism. Questioning political affiliation may lead into questioning of Christian culture and subsequent discovery that the Bible doesn’t condone followers of Jesus isolating themselves and assimilating to each other. Trying to get to the bottom of something and find the truth means you have to open yourself up to the same scrutiny. This may make you feel incredibly free, and it may scare the shit out of you. These emotions will often occur simultaneously.
