They kill Muslims every day in bombings, but not in their more targeted killings. They actually released the Turkish group specfically because they were Muslim, according to one of the Turks who was released. (Also, I think, because the Turkish company had given in to the terrorists' demands that it leave Iraq.)
It's possible that they thought he was a Lebanese Christian, or also possible that his father's request that they release him because he was a Muslim and "not a fighter" would have made it look bad if they had killed him, especially if he was deserting anyway.
On the other hand, it's also possible that they have killed him and all of this is just a smokescreen.
Ummm... I've got some oceanfront property in Arizona to sell you...
I'm sorry, but you are dead wrong about that. They released the Turks to gain POLITICAL FAVOR with other Muslims. NOT because they actually WERE MUSLIMS. They don't give a rip about other Muslims.
And they don't give a rip about one small company saying they will stop doing business with the American Military... they only SAY that's why they released them. They used those excuses to (a) gain political favor with other Muslims, and (b) to IMPLY that they can be negotiated with. But they CANNOT be negotiated with. Even if we withdrew ALL of our troops from the Middle East TODAY, and even if we completely changed our policies on the Middle East, they would simply come up with yet another reason to HATE us and want us ALL DEAD because we are Infidels. They simply want us eradicated from the planet, nothing more, nothing less.
EVERYTHING they say or do is to that end. Period. And that is why this is a war of Good vs. Evil, and a war for our very survival. (I just wonder, what if we WERE all wiped out from the planet... then what would they do? Who would they hate then? Who would they set out to kill then? There is NO WAY they would suddenly live in peace if we were all instantly removed from the planet. Like a dog that is a bully... it will be a bully no matter what group of dogs it encounters... always picking a fight, no matter what the odds, no matter what the outcome, no matter what... They don't want peace, they simply hate and want to act out that hate.)
