Historically, prayer in Public Schools was not an issue until state legislatures started passing laws MANDATING prayer and bible reading. Although Atheists get most of the blame for the resulting court cases, most of the resistance to legislation came from organized religion. All of these laws have always been a back door to indoctrination of kids. Even flag reverence and laws governing it have been little more than a way to control our kid’s thinking. You can only desecrate something that is “Holy” to begin with, so the flag on many levels is an attempt to indoctrinate children into idolatry.

The U.S. govenment should not endorse or discriminate against religion at all. The whole idea is that it does not interfere. Trump here is actively promoting religion and thus is wrong.
