I agree children are exposed to others and do not see any difference unless they come from a family that is racist or they go to school .
It is very very sad children treat everyone equally until they are taught otherwise and hear the racial slurs & since this remains an issue in the schools then O do not see it changing anytime soon.
We can only keep instilling to them that skin colour is not what is important , people that are in a different income bracket are just as important and that we are all Human and we will think learn and grow for our entire life and If we do not socialize with other cultures how can we possibly learn & grow? Even an adult that has finished college still must open their minds & learn for their entire life and if ppl remain prejudice and impose it onto their children then they are only hurting them and stunting their growth as a Human Being.
