Sorry you got upset but you were also comparing ethnicities to different breeds of dog, so I got confused.
You were the one who said they felt dumb before they went to these schools. The schools sound great except that they sound segregated. Maybe different unspecified teaching methods are more effective with certain ethnicities but maybe we should work on evaluation of all students as individuals to see which teaching methods are most effective for them.
It's complicated because I don't think it's healthy for groups to be so segregated but we also have to consider the value of keeping various cultures alive.
But what happens to cultures especially now with the Internet having to potential to create a world culture? We always seem to want immigrants to assimilate and native peoples are usually forced to change their religion, learn a new language, and so on. And then when there aren't very many left they are treated like a novelty, at least in the US. Cultural appropriation in fashion and entertainment is very popular.
Probably some kind of conspiracy.
