That still does not affect provision of rights in the same way that me standing up and shouting; "don't buy from Jews" also doesn't affect provision of rights so anyone who bring on litigation is dumbfounded.
You are free to say "don't buy from Jews". You are not free to use state funds to enforce a mandatory program that prohibits the promotion of businesses owned by Jews while promoting to students businesses owned by Christians. There are obvious differences between stating your opinion and using the state to enforce that view.
