Wow, that is long. Not going to read it now, maybe some other time. I sure hope you do, it's well worth the time. And it will reinforce your related observation that Islam isn't a monolith, which then relates back to my social psychology and the idea of out-group homogeneity bias, which sees the "other" as all the same and one's in-group as diverse ("they" are all the same, "we" are diverse). So 'Islam' is all radical jihadists, and 'Western Christianity' has many different denominations, beliefs about salvation, creeds, etc.
