If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
As I said, vague and ill-chosen.
Still, the problem remains. If you lie down with dogs, you get up with fleas. Hanson's choice to associate himself — and his audience — with people who do nasty and rude things in public and with people who espouse and practice harming others for their views is unfortunate. It is especially unfortunate in this context; it thoroughly undermines his apparent attempt to dissociate himself from some of the same.
I think vague is a cop out. The term does have a clear meaning. It doesn't exist that you can throw it out as a slur. The fact that you incorrectly slur other people to complain about them engaging in slurring has it's irony.
