Quite fine with me, so long as it isn't on the site of the World Trade center. (As said before) That lot deserves something commemorative, but the Muslims near the area deserve a place of worship as well. c:
I can see why someone would be somewhat upset if they are in a grievous state, but just because some parts of the religion aren't exactly friendly with us, that doesn't make them all horrible. It doesn't make any of them horrible. You shouldn't persecute an entire group because some are extremists. Every group has their extremists, it makes them no better nor worse then the next.
