Well, it’s someone ranting on their personal blog, something they probably never expected him to look at. It’s not quite the same as a letter sent directly to the author.

Also, an entirely different person tried to engage him rationally after he reacted to the first post, and he still dismissed that person. I understand the kneejerk reaction to someone who’s raging at you, but when you’ve had a chance to calm down and you’ve got other people telling you “No, really, this is an issue”, and you’re still dismissing everything because the first person said “fuck you” then that’s “derailing: tone argument”.

I haven’t read any unfunny wank about him before, but he did name a Native American character “Injun Joe”, so it would not surprise me.
