Well when most people think “9/11” they think about the WTC, not so much the Pentagon and PA.
As narrow-minded as it may sounds, I think it’s a slap in the face to Americans. Historically, the Muslim people would build a mosque in a city they overtook in order to show dominance. I think that that is what some of the Muslims are trying to do. I know they’re mostly a peaceful religion, but every religion has their extremists. Look at the bombings of abortion clinics and the murders related to that.
