As it relates to a school official leading students in prayer and selecting team bible verses and books to print on team tshirts?
It might be a lot easier if you laid out under what jurisprudence you think this is a gotcha?
Otherwise the answer is pretty obviously the establishment clause of the 1st amendment, the due process (and equal protection) clause of the 14th amendment, and if you intend to take a trip down the rabbit hole to crackpot town Article III.
Keep in mind Prohm was at Murray State pre Kennedy v Bremerton, so despite how Old Neil put her down, Lemon was very much in place. Even that is likely irrelevant because it would be much harder to disingenuously describe what Prohm did as a personal act outside his actions as a school official.
What I was responding to was the comment that this was Kentucky. Regardless of what radical jurisprudence one subscribes to the fact Murray State allowed all this without at least putting together some kind of cover-your-ass in case a complaint was made was irresponsible, and still would be post Bremerton. Or, you know, they could have just used the conservative and common approach of erring on the side of protecting itself and its students.
Again, in contrast, when Toledo got wind Campbell was praying with his team they immediately shut that **** down. This wasn’t, and still really isn’t, controversial nor esoteric.
