The acceptance of this declaring people as "horrible human beings" by mostly anonymous decree, and then creating a fashion where "the worst thing this did/said" is brought up by people who are X degrees removed from even that, every time the unperson does or say
anything, I find much worse than being a caustic prick, which at least is hard limited to the actions of one person. Even if the person should be really bad every now and then, they're already sometimes just kinda-bad-mumble-mumble -- and the habit that is being formed here is just waiting on being used on all sorts of people.
That I know, the rest I can't speak on. I wasn't asked to work with him or be his friend, I find his talks valuable, very lucid and much surprisingly easy to follow even with subjects I don't know much about, and in that way they feel much more respectful to me as "the" audience than a lot of the material out there.
