Atheist are the only ones able to be critical of Islam!
How so? I think a lot of people avoid it because of 2 reasons: 1. Islamic fanatics have a nasty habit of using violence against critics & 2. cowardly liberals have helped turned criticism of Islam into a race issue instead of an ideology issue.
Anecdotally, some of the most fanatical Muslims I've met have been white converts. The criticism is about the belief itself so it doesn't evaporate against a white convert.
