People tend to want to congregate around those of the same race or ethnicity. Its a natural fact, especially when children are involved. You right a long winded article pointing fingers at whites for doing so, but how do you think a predominantly Chinese ethnoburb like Cupertino (or San Marino or Alhambra) happens? Chinese cluster together near each other, obviously. But of course that’s acceptable — doing so while white isn’t. That’s “racist”.
