An interesting point of view.
Personally I doubt the guy thought so much about the potential reactions for different political groups, though. He despised a certain group of people and killed them, end of story.
People can be stupid an cruel, that's the world we're living in.
And raging against facebook or the media won't change a single thing.
My condolences to the families.
