@flippac @pathunstrom Yep, that was exactly the rationale behind that policy. And I'd explain the ban at length to other people (as long as they had a track record of reasonably genuine participation), but questioning from the banned person or his buddies would be shut down quickly.
Prevented a lot of concern trolling while still teaching a lot of other folks about how to recognize dogwhistles etc. - the flipside of that was that it cost a lot of energy initially, it only got easier later as people started explaining it to each other.
