I think you know what'd be next...bans on anything the religionists don't like. Laws requiring Church attendance. Laws excluding people who choose to practice no religion, or some "disapproved" one. Ultimately, a tiered society, with the "christians" at the top.
I think this nation is just fine. When they called it a christian nation, they were not doing things so christian. I think America is more christian now than it was in the beginning. Just MHO.
