Why do atheists and liberals like Islam?

In my opinion the Quran is much more clearly divisive and dogmatic right from the onset.

The bible is very much both of those things, but the Quran leaves much less wiggle room for doubt. And it rubs it in your face right away. It is more of an effective indoctrination manual than the bible.

Maybe this has something to do with Muslims seemingly integrating less well (in general) than Christians.
