What the Daily Caller article doesn’t say, and in fact intentionally obscures, is that the people staffing the table are not Notre Dame students. While a recognized university student group applied for and received the permit, those staffing the table are not members of that group. University policy does not allow outsiders to hand out stuff on campus, which is why they were ordered to stop doing so.
Other articles on this, to my knowledge, did not have this information...
Outside group protests gay marriage
Note that the title of this article is more a defense of Gay Marriage and comes from a Notre Dame newspaper.
They spin against Traditional Marriage, and they list all the violations by this group.
There may be TFP Student Action members at Notre Dame, and the group should have had them man the table.
But I don't understand why supporting traditional marriage is a protest of Gay Marriage -- unless Gay Marriage is something that should be promoted at a Catholic University.
