Jag and A_ahmed:
I work with Muslims. I even referred a Middle-Eastern one for a job in my lab, which she got. I know that not all Muslims are evil, but it's okay to concede that these two were.
I'm a white Christian. I know that not all members of my demographic are "saints," and I don't try to make excuses to cover for the bad ones.
Being a member of a certain race, religion, or ethnicity doesn't guarantee anything either way about a person.
