Ggreg's the nutter. He's a Steve Sailer'esque type. They're a dime a dozen, if you have any familiarity with the kosher TakiMag/Unz crowd, bombarding you with minutiae and side-tracking tactics. He wrote an idiotic article for DailyCatholic on the one-year anniversary of 9/11 trying to manipulate trads into going into the Middle East for the Jews. It says all you need to know about SD that he's the most popular member over there.
This forum has gone downhill a bit in terms of quality of participants, but it's still the best trad Catholic forum I've come across. And it's been the best since it was started by Matthew after he'd been banned (or left, I forget which) by VoxClamantis. i had high hopes for the first ABLF forum, but it got really weird over there with DawnMarie and her gang.
There's been a drain of interesting members here. You used to have people like like Telesphorus, claudel, Raoul (as nutty as he was at times), columba, spouseofjesus, gladius veritatis, PilgrimageofGrace (who mainly posted on IgnisArdens), ServusSpiritus (who I haven't heard about since he abandoned the first ABLF forum), belloc, stevusmagnus, caminus, btnyc, graham, sedetrad, perejoseph, Charlemagne, Iuvenalis, partyisover221, Ethelred, Mark79, JohnGrey, and many other quality members who weren't as prolific.
There must be some change in the zeitgeist to account for the bulk of these people no longer being here. I've read Graham on SuscipeDomine say that he's put off by the proliferation of flat-earthers.
PonDeReplay was Gilgamesh over on Fisheaters. He's always been interesting to read, but he's a bit of an actor like VetusOrdo. I never thought he was a believer.
