As a general matter I'm not at all well-inclined to those who've tried to argue that Islam is somehow an inherently violent religion. I don't think that's true.

But the following does occur to me. One hears quite often that 'Islam' means 'peace.' Not just the religion, but the word itself. My understanding though is that it means something closer to the English word 'submission.'

Similar, yes. But hardly the same thing.
