Why do you allow non-Catholics not only to post for years on end, but even give them their own subforum?
And you should be consistent as well.
Does your Trad priest deny communion to Feeneyites? If not, he's sacrilegiously giving Our Blessed Lord to non-Catholics in your eyes. You don't have a problem with that?
And if it's known that Feeneyites exist in Trad circles (Trust me, every priest knows this!) then priests should make some effort to determine who they are, if they were truly non-Catholic. He should be giving frequent sermons on Baptism of Desire to flush them out, force them to leave, force them to show their hand, etc.
I criticize some Feeneyites (Dimond Bros for example) for being schismatic -- let's not become our enemy even as we oppose their errors.
