Why do atheists and liberals like Islam?

[abaris]

We can do the same to muslims, without destroying islam.

We most certainly can't do that. They can do it, given that they get rid of the mostly authoritarian regimes, sometimes backed by us. That's the same way we went about that business. But we haven't lived under the oppression of several centuries of colonialism. We were the ones doing the colonizing. First the Ottoman empire and then the French and the British, with puppets forming the first "independent" governments.
