Unhappily, I have to agree with you.
One would think the shock of the events earlier this month would jar all of us out of our self-imposed PC lethargy. Well, it did for some, but not nearly enough. Being Liberally Minded is a habit very hard to break for those with the mindset. Outrage has pretty much died down to hand-wringing, flag-waving and calling for bin Laden's head. This war is not yet perceived as the deadly conflict it actually is. Many still look at it as an unpleasant TV episode that is already getting slightly boring.
"Pass the remote, Maude...!"
The enemy wants to bring our civilization crashing down around our heads. We increasingly seem to want to bring just a few notables to "justice" then go back to life as normal. Even the calls for addressing the "root causes" of Muslim anger are daily getting stronger in the Liberal, anti-war and Muslim communities. Soon that will be most of what we hear; ...until the next catastrophic outrage committed on our soil, which it will. Then the cycle will start all over again, but with a few more converts.
