I am not sure about the extent of racism in U.S. But I have felt much more racism in Nepal. In U.S. racism is mostly on skin color i.e. your origin.
In Nepal racism is within the same color. Do you or your children marry with kasai, sarki or damai in Nepal? Even within Newars, there is extreme jatiye discremination. I am just giving you the factual example.
Hence, let's not worry about U.S. Let's fix the racial problems in our own backyard.
Kaso?
