Unfortunately, we tend to gravitate to people who look and talk like us. It takes a desire to reach out in order for racism, nationalism and sexism to take a back seat to our natural inclination. And in fairness we stick to our own because it seems safest. This world has become too small. If you don't have friends across the board. . make some. Then you will feel comfortable among any decent people. Hopefully they will feel the same about you but you can only control you, not them.
