The only article that I found that has those details is:
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.
That article is from the student newspaper at Notre Dame, which is editorially independent from the university. I saw all of the other articles about this incident, and the reason most of them don't mention this information should be obvious, since they are taking the TFP Student Action point of view.
The article in Campus Reform linked to from the Daily Caller article actually has a quote from the Notre Dame spokesman that explains why the group was booted. John Ritchie is being disingenuous when he says he doesn't understand why. The whole "having a table" vs. "sitting at a table" is a red herring, since the distinction under university policy involves "who" is sitting at that table.
