Let me take a stab at this...First was our native American Indians, then Europeans escaping persecution in their countries. So we have American Indians and White People of European decent. Then we have Black slaves from various African countries, then Jews escaping persecution from various countries around the world, along with Italian and Irish Immigrants that faced a level of persecution and bigotry. There are others..
Every group of people that come here have faced a level of racism and or bigotry. Got to rise above it and thrive in this system.
