I suspect this is MSW's attempt to preemptively disown Bannon by labeling him "anti-Catholic." But there's no disowning him: he's a Catholic in good standing. If he's friends with Burke, it's kind of obvious he's a Catholic with friends in Rome too.

I don't *want* to own him, obviously. He's a disgrace to the Faith. But pretending he's not really Catholic is both dishonest and pointless.
