The great thing about the NCR combox is that you can flag & report nasty & vituperative comments. Pretty sure the modus operandi at Church Militant is nasty & vituperative, so you're out of luck there. I mean if Archbishop Chaput doesn't measure up, who does?

With regard to the particular posters you're replying to, as someone who has frequently been on the receiving end of some of the jabs, my advice is to ignore it & move on. Nothing forces you to reply to the comments. Simply turning a blind eye can be the prudent course of action.
