So, let me get this straight.
A man who has published a dozen books (many of them explicitly on apologetics topics), edits a magazine that is at least partly devoted to apologetics, and who has publicly debated (among others) Michael Horton and Robert Godfrey, is supposed to be so afraid (we are told that he "turtled") to get into an apologetics conversation with TF's friends that he "locked down" (that's my phrase, not TF's) an apologetics website forum by adding a registration requirement?
Meanwhile, back in the real world, wouldn't it be possible and even likely that Madrid & Co. have other plans for the site besides dealing with literally any stray Protestant critic who comes around the bend? Is it more likely that TF's pals are going to ask more searching questions than seminary professors from Westminster of all places?
And if you're going to suggest that the registration requirement is intended (oh yes, TF knows the hearts and minds of Patrick Madrid and Co.) to prevent others from "shin[ing] any more light on the deception routinely attempted there [sic]," don't you think you'd be in a better position to do that if you didn't have a registration requirement for one of your own websites? Or shall we conclude (following his own remarkable example in this case) that TF has "encased" that site "in a protective shell of registration, lest outsiders shine any more light on the deception routinely attempted there"?
Well, let's not do that. Let's concede what TF won't concede about Madrid: namely, that we don't know what TF's reasons for the registration requirement are, but that he probably has what he thinks are good ones (as opposed to cowardly ones).
