Believe it or not, using the phrase "politically correct" as a modifier does not actually work to stifle the argument... unless you're preaching to your own choir.

Name instances of "Islamic terror" that do not have something to do with a real political or economic conflict with the target of the attack... or a grievance related to problems in the Middle East. And then explain to me how it is that "Islamic terror" is different from other forms of terror and how it is similar to peaceful adherents of Islam.
Seems to me "terror" is the operating word. And if you knew even a little about terrorism you'd know it is typically a manner for gaining political/economic power... most typically used by people with no legitimate means of attaining that political/economic power.
And it looks the same no matter what ideology it is painted with.

Exactly how does one not "let religious zealotry run amock"? Religious zealots are just as free to run amock here... but they tend not to, at least not in the ways you're thinking (which goes to show zealotry is not always related to terror).
Perhaps it makes more sense to focus on why religious/ideological zealotry in the violent sense is an attractive option to more people in some areas than in others.

This is the most moronic step that comes out of this "WW4" neo-Reaganite mentality... the willingness to collectively punish an entire population because there are some involved in every war around the world...
So your belief is to attack the innocent within in hopes that somehow it will terrorize them into breaking from the bad guys- who they don't really like all that much anyway!
If there was any brainpower involved in this idea it would involve attempting to SEPERATE the majority of Muslims from the bad guys by giving them incentive.
Rather this mentality is set up around LABELING ALL MUSLIMS as bad guys, thus making us the very COMMON ENEMY the terrorists need to keep their recruitment up.

That's not true of all Muslim communities. But of course it's important to note that the areas you see these problems with have not had the benefit of a history in modern representative government.
The details take time. Our country wasn't exactly perfect during its founding.
But one thing's for certain. Being imperialistic and condescending and thereby making ourselves the common enemy of all Muslims... well, that's not going to do much to bring progress to their countries.
The fact that people with your mentality exist almost makes me glad we wound up with Bush. At least the neo-cons don't adhere to the ridiculous notion of war against Islam. Rather they at least try to make friends and see progress in the countries (albeit in a condescending and semi-imperialistic manner).

By the same logic I can label all of you religionists as nothing but part of the same cult of theism. You all seem equally anxious to grab for political dominance by whatever means necessary (your post is an example).
All god-worshippers are the same if you want to go at it from that angle.
