As individuals we all have our own hardships and tragedies - some obviously a lot more than others.

But there's no amount of injustice that you can suffer, either as an individual or as a group, that justifies acting like a murderous savage. There's no need for "but (x) did this" conversations.

This Abdul guy was a murderer, a piece of shit. Those who commit war crimes in the middle east are murderers (but a distinction between war and war criminal must be made).

To argue about who did what to who is irrelevant: a man who chooses to purposely kill innocent civilians is a savage, regardless of his color or religion. Let's call a savage a savage and move on.
