Forgive me for stating an overused statement, but deranged individuals DO NOT represent Islam as a whole.
Just as good Christians cannot reign in the people of the Westboro Baptist Church, or good Jews reigning in the ultra-Orthodox Jews (the Haredi Jews) in giving newborns herpes, good Muslims (and yes, they do exist) cannot simply reign in extremists.
No-one, unfortunately, ever has control of extremists in ANY religion. That being said, banning Islam because of extremists is absurd.
If one was to ban Islam, then Christianity and Judaism should also be banned for the same reason.
I understand the point you are trying to get across, but I do wish you would see Islam from an objective point of view, free from the absurdities of the Western media and see that Muslim extremists are not truly Muslims.
In fact, in my opinion, this awful and mentally unstable man was not a Muslim. The rambling psycho quoted Exodus 21:24 "Eye for an eye" rather than the Quran.
Furthermore (not related to the quote), these "terrorist" attacks are constantly elaborated as the work of Muslims and yet there are so many other frequent attacks ON muslims by people of OTHER faiths that is, for some illogical reason, always swept under the rug.
