The thing is: They know that its pouring salt in the wound. Thats why they shouldn't do it.
Do you, uh, do you have any evidence for this claim? At all? Other than they're brown people so they hate us? Because here's a quote from the first thing I found on Google:
The man spearheading the center, Imam Feisal Abdul Rauf, is a moderate Muslim clergyman. He has said one or two things about American foreign policy that strike me as overly critical —but it’s stuff you could read on The Huffington Post any day. On Islam, his main subject, Rauf’s views are clear: he routinely denounces all terrorism—as he did again last week, publicly. He speaks of the need for Muslims to live peacefully with all other religions. He emphasizes the commonalities among all faiths. He advocates equal rights for women, and argues against laws that in any way punish non-Muslims. His last book, What’s Right With Islam Is What’s Right With America, argues that the United States is actually the ideal Islamic society because it encourages diversity and promotes freedom for individuals and for all religions. His vision of Islam is bin Laden’s nightmare.
