Sure I have. And sure he is. But like I said I have seen nowhere near the level of criticism of his bigotry (or even awareness of it) as I have seen coming out of skeptical, science, and atheist communities. And from the left in general.
Fact of the matter is. Having spent a lot, like a lot, of time reading up on the subjects. Creationism is shot right through with very old racialist ideas. Evangelical/fundementalist Christianity is deeply mysoginistic. And the religious right is one of the prime drivers of the clash of civilizations/religious war narrative when it comes to Islam. (Curiously the same argument the Islamic fundamentalists are making).
I stopped reading Dawkins years ago. Because I saw him making the same arguments, behaving the same way. As those folks when it came to these subjects. I suspect there is less noise about Dawkin’s views on those subjects from the religious right because on those subjects Dawkins and the church nuts are at least loosely on the same page.
Whatever I have seen seems to be shallow, hypocritical aping of criticism and controversy started elsewhere.
