I'm just talking about Texas. I lived in rural Louisiana too and the teachers at least stayed away from religion there. I live in rural Massachusetts now and I'm sure there are a few but they wouldn't be fanatics like the Christians I knew in northern Texas' schools. Texan Christians outside of big cities do what suits them and because there's virtually no alternate viewpoint they're unquestioned. They won't stop you from not being a Christian, outside your family, but people will look down on you. Although none of this applies to Jews; there tends to be sucking up to Jews in America.
I didn't read the article so I only left out the part where the student was invited to the White House.
