It’s not like they came to protest at your house. They were simply walking onto the grounds of a major university, one which has no problem identifying itself as Catholic, making tremendous merchandise out of that famous identification. It is run by priests who are completely under the authority of their Church, supposedly. That Church decries the evil of abortion, and Barack Obama is the most prominent and powerful propagator of abortion on the planet. Inviting him would be as if the NAACP decided to invite and honor the head of the KKK. Think maybe someone would get upset at that?
People are technically wrong in calling this civil disobedience. The protesters are not challenging an unjust law, per se, even though it is taking place in the larger context of the abortion holocaust. They are in the first case here protesting the actions of their own Church in allowing honors to be bestowed on someone who is not in the least honorable. And those who operate under the authority of their own Church had them arrested.
