I don’t like the way you’ve phrased all of this. What children need to be taught is to treat people how they find them, rather than this ‘accept adversity’ bilge. Note, I do not like the word ‘accept’. The fact you’ve used it acknowledges the big issue of our times. You know it’s a big issue but just accept it, yeah? You have no choice but to suck it up.
It’s also slightly amusing you posting this. The schools where you have to ‘accept diversity’, because you’re the minority, are schools in white flight areas, so issue solving itself in a way. In schools where there is quite a mix of continents, because that’s what it is, there’s issues coming from any of the continents towards one of their other continents at school.
You didn’t have these problems before. Ethnic minorities had no choice but to integrate more. Now they do and you get issues through teenage and adult years, but you wouldn’t notice down in Truro.
