What, more comfortable thinking that EVERY single person in the world that I walk by every single day could potentially be a murdering psychopath capable of exactly the same thing regardless of religion, race or belief system?
You think that I'd be more comfortable if I can safely subsection society into groups that are more likely to perpetrate crimes like this, such as Muslims? You might be right - it is far more easy to form an us vs them approach to bigotry.

the IRA splinter groups exist too
really don't see you point nor how you can bury your head in the sand and claim this has nothing to do with Islam
just because Islamic terror exists doesn't mean other terror groups don't - but failing to acknowledge it and denying the role of fundamentalist Islam on the basis that lots of other muslims are nice and not terrorists is just ridiculous
