As for whether it's worse in other countries... I don't think you get to make that determination without being a visible minority. Certainly, ethnic violence and racial violence are akin but not the same, just as treating people as second-class citizens based on the color of their skin is akin but not the same as treating customers as second class citizens because you don't like the strength of their OS's security standards, or don't want to hire Android programmers, or whatever.
Bluntly, I didn't need to be a Turk to notice how Germans treated and talked about Turks, or to compare that to how white Americans treated and talked about minorities.
