Aside from its traditional meaning, 'Church Militant' has become a code word for an ugly strain of intolerance in the name of what you term faux-traditionalist Catholicism. I don't know to what extent, if any, Steve Bannon associates himself with all that or with Michael Voris, but I am confident that as a media-savvy person, he understands the implications of tossing the term around.

I'm not sure where MSW is coming from, but Bannon is Catholic. As for the allegations of antisemitism, etc., they seem to stem more from comments others have made on the Bretibart site than those of Bannon himself, the implication being that his failure to refute or remove such comments suggests personal consent.

I withhold judgment on all that, but I have learned enough about the man to believe he's unqualified to be a presidential counselor. But then, the president he'll be counseling is also unqualified, so I suppose they're a match made in... well, somewhere south of heaven.
