Tolerance

I'm not generally a big fan of Texas Governor, Rick Perry. But in a recent speech in London on the global threat of Islamic terrorism, he said something that I think is very important:

But to every extremist, it has to be made clear: We will not allow you to exploit our tolerance, so that you can import your intolerance. We will not let you destroy our peace with your violent ideas. If you expect to live among us and yet plan against us to receive the protections and comforts of a free society while showing none of its virtues or graces then you can have our answer now: No, not on our watch! You will live by exactly the standards that the rest of us live by. And if that comes as jarring news then welcome to civilization.

Given the recent atrocities perpetrated in the name of Islam by ISIS, given the threats against the homeland espoused by Islamists in general, given the many hotbeds of Islamist support in the West in Mosques and among Islamic advocacy groups (e.g., CAIR), and given that Barack Obama and his leftist supporters espouse "tolerance" above all else, why is it that a governor from Texas is saying these things, but the president is largely silent? For that matter, why haven't the many Muslim "moderates"  that we are told represent the vast majority within Islam said the same thing—loudly, publicly, and frequently?
