“I’m not ashamed to admit that I’m a Christian,” the Texas governor says in the spot. “But you don’t have to be in the pew every Sunday to know that there’s something wrong in this country when gays can serve openly in the military, but our kids can’t openly celebrate Christmas or pray in school. As president, I’ll end Obama’s war on religion, and I’ll fight against liberal attacks on our religious heritage.”
But everybody can openly celebrate Christmas! They can pray in school! They just can't require that the school force everybody to do so. Obama's "war on religion"—to the extent that the president has even been part of these culture wars, which isn't much—only means that Christians don't have a privileged position in forcing the rest of society to observe their rituals.
Not that I expect to persuade anybody. There's a variety of Christian who believes that if they're not allowed to dominate society, they're being persecuted. These folks vote Republican.
