A question: how is it wrong to say "most murderers are men, therefore manhood is murderous" but not "most terrorists are Muslim, so Islam is murderous"?
Why do you think most Muslims are terrorists?
Because of 9/11 and Charlie hebdo and whatnot, it's self-explanatory.
Those events were awful but it is not good to generalize and think all Muslims are the same. There are many terrorists from other races. You wouldn't want to be accused of something that some people that share your faith or race do, right?
I wouldn't care if people I hate were accused.
There are some Muslim terrorists, this is a fact, but it doesn't mean all Muslims are terrorists. It's bad to generalize an entire race of people like that.
