That may be very well true, but the link also serves as a counterpoint to those that want to make ground zero into something it isn't.
And to make another point. Not all of those who lost someone at ground zero feel that the mosque shouldn't be there.
There is no clear right or wrong or unanimous decision when it comes to this issue. As i said earlier, the OP's suggestion for other buildings around the mosque would certainly fit right in with the neighborhood.
Once again, within the context, the mosque is offensive to the majority. The WTC towers were not attacked by nutjobs claiming religious jihad for strippers, cheeseburgers or t-shirts. I'm pretty sure that those who are not offended by the proposed mosque site, would also not be offended if it went somewhere else.
