Well clearly many people disagree that is an actual reality to today, and if it is the problem would be a symptom of a much deeper issue not addressed by the bill at all, and in fact would probably make the root cause worse

That is today we seem to be moving away from the "melting pot" of multiculturalism were we are all one nation made of many, to a salad bowl of multiculturalism where we lose the "one nation" part, and communities are splintering / siloing themselves off from one another inside one geographic bloc

We need the melting pot to return... that is the only way multiculturalism actually works.
