We had a look at Richard Dawkins a little while ago. In his case, I concluded that whilst he’s been hanging out with the wrong crowd he is in all likelihood, not evil. But he does appear to have made some new friends who are not quite right. Unsavoury, even.
At the time, I compared Dawkins to Sam Harris, who is prone to gaffs, except in Harris’ case, it just seems to be his own case of peculiar logic. I also consider Harris to be largely benign, although Harris lost a lot of his own cred when he tied himself in knots over racial profiling.
Where Dawkins and Harris have it most wrong though, is on the subject of Islamophobia. They're not the only ones: I know of quite a few in the atheist community who think that Islamophobia does not exist.
