Why does the media portray Muslims to be extraordinarily violent?

Especially when Israel has now killed nearly 500 in the strip and the US is responsible for 1/2 million Iraqi deaths. Sure ome muslims are violent but isn't it once again, unfair to group a certain people as collectively violent? The violent hotspots in the middle east happen to be where christians (US) or jews are either invading or occupying, or oppressing. You go to dubai, abu dabi, life's great??
