I'm afraid more bishops care about the rights of illegal aliens than are willing to do more than give lip service to the pro-life cause. Otherwise the list of bishops denouncing the University of Notre Dame would be much longer.
“Are you saying that a private college affiliated to a church is required to allow someone to speak there whose views they don’t want to hear?”
You are correct. They arent.
It’s also probably correct that Tom Tancredo is a more serious and devout catholic than most of the faculty at this college. Its also correct that the college certainly is allowing many speeches and expressions that are contrary to church teaching on campus in the name of free expression ... “Free speech for me but not for thee.”
