These terrorists are no more a true muslim than you or I mate. They use Islam as an excuse for their hatred. The religion doesn't use the people, the people use the religion. It's an important distinction to make, and one that sadly most people (on here at least) don't seem able to grasp.
They are thugs, murderers and scum. And they deserve everything they get when tracked down. Don't let that make you hate proper Muslims though, because if you do, then you're playing straight into their hands.
It's a wicked, but simple cycle. They associate themselves as Islamic. They bomb and kill. People who fall for the ruse that this is about religion start hating proper, peaceful, muslims who abhor the violence and death as much as we do. The terrorists then point to the 'hatred of the white man for the arab' and stir up more and more willing suckers to their cause. And all because they hate us in the first place - whether it's because we have the better land, more money, a far higher quality of life, longer life expectancy, or whether it's due to some perceived injustice either recent or historic - doesn't really matter.
The one certainty is that this is NOT a reflection of Islam. And reactions like some you see on here is just making everything worse - which they love.
