Carefully screen the private schools and even Catholic schools. Some are just as bad or worse than many of the public schools about these issues. There are still a great many conservative areas and the public schools are not nearly as prone to this stuff in those areas. The district I was in before this one, we even did sing around the Christmas tree and performed the nativity story ever year. Many of us teachers kept Bible verses up. No one had yet complained so it was no issue. If you live in an area prone to these issues, many times it happens in the Catholic and private schools as well. Partly because the people that pay full price push it through (and they run the schools), partly because the schools are afraid of lawsuits, and partly because some schools are basically just a safe haven for rich “non judgmental” families. Problem is, their non judgement is actually them judging people that don’t agree.
