Why is it always Muslims?
One need look no further than the content of Q'uran and Hadith and the manner in which they spread from Arabia like a cancer and the barbarism of their cultures.
Again, Christianity has been responsible for Imperialism, the Native genocides of the Americas and Australia, and two world wars... if anyone is bothering to keep score.
"Gott Mitt Uns!"
And once again all's you can do is point to past atrocities that no one currently living is connected to.
This isn't about "keeping score", it's about WHERE the threat of terrorist acts is coming from TODAY, and TODAY the threat is coming from the members of ONE religion. I-S-L-A-M !!!
Actually, the threat is that we keep arming them, getting in the middle of their politics and wondering why we get stung when we stick our dicks in their hornet's nest.
And even then, we've killed more of them than they've killed of us.
