Sometimes it's easy to answer these buffoons. Unfortunately they still (or don't want to) get it because they keep peddling the same old crap over and over again. The only people they convince are themselves.
As far as banning gods from (public) schools maybe they should read the constitution.
Said this before and I will say it again. My kids even post in FB about the shootings happening because we banned god from our schools. OK, I'm 74 years old and the only school prayer I remember went like this - "those that want to can now do one minute of silent prayer and then we get to work." Strangely, those my age that I went to school with claim they can remember school prayer. They are lying. Prompted often by the preacher, they are lying.
