Which does USA fear more-communism or religious fundamentalism?

Both Communism and religious fundamentalism scare the crap out of me. Religious fundamentalism is basically Socialism, which is a step toward Communism. Most people understand what Communism is but they don't understand religious fundamentalism, how it works or how it creeps in slowly using free countries freedoms to invade the country. I believe the problem here is that many people welcome Socialism as Obama offers it because they want the government to take care of them. He won't call it socialism but it's the same thing. It's not only taking over Pakistan and Afghanistan but also Somalia and working toward the U.K. It's pretty much taken over all of Europe and people here just aren't very interested in learning about Sharia Law and what it implies.

The USA says it fears as much of one as the other, but little do American politicians seem to realize, Fundamentalist Christians are all over the States, and causing a lot of the same extremeist problems as fundamentalists of any religion would cause. Americans want to think that church and state are not combined, but fundies are turning the USA into a Theocracy.
