Thanks for pointing that out, however I disagree that not talking helps.
I see how it goes in Portugal and the few European countries I lived in, including having experienced myself xenophobism in first hand in some of those countries, and stop talking isn't how it gets sorted out.
What is your end game? If you want something to eventually disappear, then it must eventually disappear from common discourse. Otherwise society keeps fanning the embers of hatred.
Naturally we also have our issues on this side as well, unfortunately.
