It is the central dynamic that perpetuates all this violence. Someone from Group A kills dozens or hundreds of Group B, which uses the violence as an excuse to oppress thousands of Group A, which uses the oppression as an excuse to kill more of Group B, and this goes on and on for decades long after everyone's forgotten who "started" it or why, because both sides have convinced themselves, against all logic and evidence of history, that if they just hurt the other guys enough they'll give up and be nice.
It is never going to end until we find a way to break the cycle. The only way I can think of to contribute is to be a voice condemning the violent bigots on both sides, and trying to separate them from the millions of innocents that they claim to represent. It's not much. It probably isn't anything at all. But what else can I do?
You're just perpetuating the nonsense. Yes, you're against it, but your comment is little more than the sentiment you're against, plus a statement of opposition.
