Yes it is. That distinction is entirely subjective. If the government declared that the idea of a virgin birth, the trinity, Jesus being the son of God, miracles, the crucifixion, and the resurrection were all "superstitious nonsense" but didn't explicitly call Christianity "superstitious nonsense" would that be OK?Attacking a single viewpoint of a religion is not an attack on the religion.
So what? Just because SOME people believe one thing doesn't give a government official the right to criticize others who don't.There are lots of Christians that believe in evolution and the laws of physics.
No one is suggesting they should. That has absolutely nothing to do with the subject of this thread.But teachers should not tolerate falsehoods to be taught in the schools.
