Reaganfan was banned at a time when moderators seemed to be actively looking to ban certain posters (and getting a lot of backup from the some of the worst of the Left here). Why exactly he was permabanned I don't know, but it came not long after Famous Mortimer was permabanned. After he was permabanned, a few of the worst here suggested that I should be permabanned next.
Naso and Mortimer were completely different situations from you. I wasn't a mod at the time but I supported and still support both of those bans. I vigorously opposed the idea of banning you then and vigorously oppose it now.
Reaganfan got overtly antisemitic. The posts can't be accessed now because, well, they were deleted, but they were
bad. With Mortimer the problem--and the reason an admittedly somewhat threadbare excuse for his ban had to be trotted out--was that he deliberately spaced out racist, sexist, and religiously prejudiced remarks (including against conservative Christians on at least a couple of occasions!) widely enough that the normal pattern of escalating sanctions couldn't be implemented. This has been an attested strategy of evading mod action on this forum for a very long time, so it isn't something that the mods just made up while attempting to wrap their heads around Mortimer's posting style.
