These legislators will cut their nose off to spite their face. These states that are starting to add the 10 commandments to every classroom, require teaching the bible, etc, are they going to be ok with requiring the Quran to be posted as well, adding the Satanic bible to be required teaching, etc?
How much common sense is it to just keep the types of religions as a unit in history, let the FCA, type clubs keep meeting as long as it is student led and non mandatory, and allow the see you at the pole type things go on before school and again, non mandatory. I have had several preachers, teachers/admins, and legislators say the exact same thing. You either have to allow for none or allow for all.
