Um, islam and peace in Arabic both come from the Arabic root س ل م, so to say that they aren't related is just wrong.
Most religions have/had a very strong violent aspect directly related to them. (Crusades, Israel's Torah "backed" colonization, India creating a hindu state, etc.).
Everyone is free to believe what they want but imposing something on others is not cool :/
Couldn't that be called subconsciously wanting to fit in?
