If you want to live in ignorance then don't expect real schools to rubber stamp your stupidity.
Now, about the whole school-thing. I myself went to a christian high school, and even though the school was based on christian values, non-christians were accepted. In fact, about half the students were non-christians. If christian schools started to refuse allowing non-christian students into their schools, thousands of people would be on their asses within a few hours. People have a way of looking at christianity as a faith, and atheism as what's true. Let's not forget that atheism is also a belief, just as christianity.
