Look! you can find people practising descrimination everywhere. Please do not tell me that it's not happening in wastern countries. I do not think that I should remind you rioting in France and Australia. The racial profiling is pretty official and they are more concerned about muslim than anybody else.
As far as not exposing your children to this land of descrimination, it's your decision. You are probably married to a white guy and so, you can do that. Renouncing anything is not a solution. There are thousand of people trying to improve their society. Please do not spit on their face. The difference is that you are running away and several people are staying behind and trying to make it better.
