I agree with that. I do say, however, that evangelical atheists have a worldview and a belief system which operates in many ways like a religion. To attempt to rigorously scrub organized religion out of the fabric of society (as some people do) is tantamount to establishing a religion.
Mind you, I don't think the teacher was establishing anything. But in a broader context, I do not think that the intended purpose of the First Amendment was to create a world in which Atheism triumphs over all other worldviews.
“To attempt to rigorously scrub organized religion out of the fabric of society (as some people do) is tantamount to establishing a religion.”
Not really. The original intent of the “establishment clause” was obviously to prevent the establishment of a church, of organized religion. Besides, I think it’s an insult to organized religion to call unorganized religion “religion”.
