Most of his challenges were assessed and struggled with exegetically, sometimes in great detail. I am entirely sure I wasn’t sidestepping his challenges when I answered them in great detail, for example (although I wasn’t active on all his threads), but he routinely sidestepped my counterpoints and counterchallenges.
While his most recent threads are currently locked, that’s to prevent people from dogpiling him now that he has no possibility of defending himself. The threads are still there, with allllllllll the discussion that was on most of them. (A few were so new that there was almost no discussion yet.) Members and visitors are entirely welcome to read everything he had to say, and everything his opponents had to say, at any time; and to pick up his arguments if they want. Although I recommend they do so with an eye to keeping in mind what was already said against them and proceeding from there.
Otherwise those people won’t be assessing and struggling with the challenges but merely dittoing them as though nothing had ever been said on the point. Which frankly was something Aaron routinely did.
(Also, only his most recent threads are currently locked so far as I know. Once I got beyond the threads active for the past seven days I went home for the night. I may or may not get around to locking the other ones, or other ad/mods might. That’s why I said “at our convenience”. The process is a bit tedious.)
For people who don’t know where the ban occurred, it was in this post of that thread. (There will most likely be an official statement posted later once we’ve chewed the matter over and decided how long his ban will actually be.) Considering that I spent a lot of time and work answering several of his challenges in careful and nuanced detail (including in that thread, by the way), and considering that I banned him for blatantly lying about charging another member with intentionally lying against God like Satan, I can say as conclusively as possible that the problem was a behavioral one and not a sidestepping of his challenges.
Having said that, I do admit I would rather be working on discussions with other non-universalists on the forum, namely Paul, Chris and Chad, than to be spending any more of my limited time and energy working on detailed replies to him. But that’s because they aren’t only more good-natured, they’re far more competent as challengers. (And besides I could always just ignore Aaron and work with them. I don’t have to ban him to do that.)
