So let us pivot from the "Catholic progressives here" to Berkeley students and Maxine Waters.  Then, having redefined the category of people involved to include whomever, let us reach a conclusion and declare it is not opinion, not mere belief, but fact!  Why bother with logic, when there are so many creative ways to justify one's beliefs?
I am opposed to violence and believe the actions of the Berkeley students are an affront to freedom of speech.  I guess you are unaware of the ACLU's condemnation of the suppression of speech at Berkeley?
