The Trump thread in Current Affairs /IMHO has been an echo chamber for a long time now, which would be all right if it was self-policing with posters reporting any posts that cross the line. But that doesn't seem to be happening, instead if anyone wanders in with an opinion that isn't part of the echo chamber, I presume they get mass reported, then pick up warnings or bans for things that would go unnoticed if they were part of the clique,
If it looks like a free-for-all to outsiders and then they participate in kind, only to pick up a ban... you can understand where accusations of bias might come from.
