So you are saying we should help the Taliban by showing intolerance rather than having their argument blow up in their face over our tolerance? They have been pushing the 'America is so intolerant' rhetoric in their arguments so much, it would be pretty bad for them if we allowed it. I can see the explanation now:
"I know we said America was an intolerant, Islamophobic society, but you know, they let a community center with Islamic ties be built two blocks from Ground Zero. Death to the intolerant americans?"
So, what do you want. Show the rest of the Worlds Muslims we are intolerant. Or gain the support of most the worlds Muslims and really piss off the ones who attacked us? I think the answer is pretty clear.
That's pretty much the whole argument by those who hate our American freedoms.
