All of that would make sense but when you consider that a quarter of Muslims in the UK believe that the Charlie Hebdo cartoonist had what was coming to them, you can't point to oppression, political instability and other geographical exploitation's as being any kind of driver.
Similarly, many westerners believe (as you appear to) in all manner of essentialist rationalisations for the relative economic misfortune of minorities in western countries, the relative prevalence of war in the Middle East, etc etc.
It's not hard to look at AIDS and conclude it's God's punishment for homosexuals, if that's your Weltanschauung.
It's not hard to look at history and conclude "hey maybe half a millennium of colonisation, slavery, political oppression, warfare and economic tyranny have something to do with it", but there are lots of less uncomfortable conclusions.
Are there more deaths in the street due to religious insult in Pakistan than there are multiple murders in the US? Is it reasonable to conclude from a long pattern of incidents that all men in the US are homicidal gun nuts?
@[deleted] it's literally the first thing I said above, but others have immediately dragged the topic back onto Islam despite the fact the latest killer was a Christian-turned-atheist!
