As someone who regularly checks EoEO and WE, and have been the witness of some EoEO bannings, I have to say Staff's done a pretty good job of it. They don't ban views - they ban the way that that view was expressed. At least, from my experience here, and I've been around for a good long time.
I would have to agree with this banning if that thread was, in fact, made soon after his death. It wasn't a perma-ban, it was merely a temp-ban to show you that there are more reasonable ways to express your opinion.
