Wish all adhered to this statement:

“Catholic identity," Garvey said, "is ‘not just marketing’ or ‘a vestige of our founding’ but ‘integral to who we are.’”

And they will be expelled if they violate?

Nice idea, but I don't think it's enforceable.

DominiSumus: I don't think so either...

it may not be enforceable but it is important to make the statement of principle.

DominiSumus: do you mean legally or just that it'll be very difficult to enforce in practice?

It's nearly impossible to enforce in practice. I also doubt the school refers to it as a "ban". When a school bans something, there has to be a consequence for the violators.

Exactly MrsMontoya It is nice to see in light of what other "Catholic" schools are stating and/or doing.

Not sure it's so unenforceable. They have separate dorm buildings for men and women, and school conduct contracts have been enforced pretty readily before.
