Feed unfortunately that's not strictly true about Buddhists. There are currently awful atrocities being carried out against the Rohinga (Muslim minority) in Myanmar. Really sickening stuff but it seems to get almost zero publicity here.
And therein, I think, lies the problem. I have lived in the Middle East so I know for a fact that people are just as appalled as we are by the targeting of innocents. They are, however, acutely aware of the hypocrisy of Western attitudes. The vast majority of victims of Isis are Muslim and it passes nearly unremarked, as does the absolute catastrophe in Yemen. Yet when it's us, then it's suddenly beyond the pale and something must be done.
Of course it feels more hurtful and shocking when it's close to home. That's understandable. But I wish people would open their eyes to the global picture, because it's all connected and affects all of us.
And there is never any excuse to use the language of the Third Reich as you so rightly say.
