Am I Missing Something?

So there's a lot of outrage about some people wanting to build a mosque near where the World Trade Center used to be. Why?

I get that Islamic extremists were responsible for the attack that killed so many innocent people, but Islamic extremists are a minority within the Muslim community. Or, at least, I'd like to think they are. From what I've heard, it sounds like the guy in charge of the mosque that's being built there is a moderate Muslim. You know, the kind you'd encourage all Muslims to be like.

Would there be this kind of outrage if someone wanted to build a church next to an abortion clinic that had been bombed by some nutjob who decided to kill people at an abortion clinic to prove that life is precious? Using the logic surrounding the WTC mosque hullabaloo, all Christians want to bomb abortion clinics. Since I'm a Christian and have no desire to bomb anything, I know that to be untrue.
