Stephen Walt, Harvard IR professor and regular blogger @ Foreign Policy provides a trenchant analysis and critique of the positions taken over the so-called "ground zero mosque". Those who oppose it go against the grain of religious freedom and toleration that we should cherish, but many of those who don't oppose it show a degree of excessive—and disheartening—political expediency.
* I use the term "ground zero mosque" or "mosque at ground zero" even though, as Walt points out, it is neither a mosque nor is at ground zero. We have here a prime example of how a label can define reality, instead of reality requiring the label.
