If pushed by any level of government it’s a first amendment violation. In all cases, favouring one religion (or group) over others is discrimination. By making it an example of coercion, it poisons belief making it a must do rather than a wants to do. The only good that might come from it is having an example of how not to handle interactions between groups.

The best way to fight this is to start saying we can only support true Christianity - Jehovah Witnesses or Mormons. The evangelicals that push for these kinds of things hate those 2 groups
