He had an issue with Ben Stein's movie, and he never looked back.
I never saw the movie, but it sounded silly. But that is not a reason to go silly yourself.
And a lot of the anti jihadist also went kind of racist about arabs. I have a little issue with that myself. But I also have a big issue about how Islam behaves. I stopped going when he went weird about Ben Stein, I kept checking in, but by October, I just plain removed his bookmark.
Tis a pity, because when he was good, he was great.
