The notes were different but the chord progression was the same.
I don't think wildly inappropriate heuristics for the treatment of others is particularly distinctive of Americans... Even and maybe especially odious racial heuristics are not distinctive of Americans. Everywhere else I've been in the world, the racism that rears its ugly head there is way more blatant and open than what I've encountered at home. It just does so less often because there is more demographic homogeneity in other countries.
Having heuristics derived from evolving in small groups for a very long time (which are inappropriate in the postindustrial environment we have fashioned for ourselves) seems like more a human characteristic than an ethnic or national one.
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.
