"Carefully read what I wrote and then attempt a cogent responce."[sic]

Got it.  Here's my cogent response to your above statement: 1) You spelled "response" incorrectly.  2)  You didn't pick up on the clearly-evidenced sarcasm.  3) You took my original percentage as literal instead of hyperbole, which tells us something about your critical reading skills. 4) You should have taken that percentage to mean, "The clear and overwhelming majority of cases," but you didn't- which further tells us something about your critical reading skills.  5) Your response was driven in all probability out of laziness, not stupidity: instead of replying, "You know what? You're absolutely correct- the clear and overwhelming majority of modern day terrorism is, in fact, made by Muslims." You instead challenged the percentage given, which indicates triteness and a lack of argumentative skills..

That's about as cogent as I could make my response, given the material I had to work with- hope it works!
