I've already stated my reasons. I'm still the all-time top poster here on CI (sort by number of posts in the Members area).
1) Croix has turned the forum into a total joke. He gets "banned", comes back, the Moderator knows he's back but just laughs it off and then lets him run amok again, and his behavior is puerile and idiotic, lowering the level of discourse here by many notches. He also could very well be a fed, having boasted of access to various non-public sources of intelligence, and making such over-the-top comments as to be nothing short absurd caricatures of the worst kind of racism ... that only someone trying "too hard" could even cook up, i.e. attempting to act as an agent provocateur could ever make such comments (short of his having serious psychological problems).
I find it embarrassing to participate in this stupidity.
2) Several Posters (mostly the sedevacantists) here who get away with slandering public figures with impunity, alleging that their conversions are fake, that they're Masonic Luciferian sun worshippers, and infiltrators ... and this is key ... WITHOUT a shred of credible evidence for those claims, clearly just made out thin air over bitterness about the fact that their targets are not lifelong sedevacantists. While certain amount of speculation and theorizing, based on actual evidence, can be helpful and useful, the allegations that are simply made up cannot be excused of calumny and/or slander. But the calumn and slander continue with impunity here, and I will not be party to it.
I find it morally repugnant to see the torrents of slander and calumny issuing from those who pretend to be morally superior Trads.
3) Increasing frustration over people who string together one fallacy after another, often blending in lies ... in order to justify positions they've taken for various emotional reasons, and then, after being, corrected ... simply regurgitating the very same fallacies.
I find that I need the old "Glenn Beck" duct tape wrapped around my head to keep it from exploding.
