Atheist Scholar Phil Zuckerman: OK to Criticize Christianity, but Not Islam

You should read both the article and the comments.
I could be wrong, but my hunch is that Zuckerman is probably right. Also, I don’t know this for a fact either, but I suspect that the same fear which stifles atheist criticism of Islam also stifles Christian criticism of Islam. Yes, there are atheist and Christian critics of Islam, but it seems very easy to believe that there are less critics than there would have been if Islam did not have the kind of reputation it does.
Speaking only for myself, I’ve written almost nothing about Islam. I know very little about it, don’t come from a Muslim background, and don’t live in a Muslim country. But supposing I were an ex-Muslim living in the United States, I would probably have to think twice before openly criticizing it.
What do you think?
