Separation Of Church And State? Selective Application

SEE HERE Apparently the public schools are prepared to teach about any religion except Christianity and teach propaganda at that. I'd get my kids out of the public school as fast as possible if I had any young enough to be in there. They don't learn to write cursive, they don't learn to read very well, they can't do arithmetic without a calculator but they can tell you that Egypt was better when it wasn't a democracy and now the Muslim Brotherhood has saved it. Can we have a little more education and a lot less indoctrination. Please!
