Does your circle of friends exactly match the general population demographics? No? You're a racist!

See how absurd your expectations are?

While that's a false comparison (there aren't lots of people trying to support their families by becoming my friend), bubbles are very real. Communities tend to be racially segregated and that leads to prejudice and discrimination.

Please be a little more receptive to stuff like this. Racism and sexism are social ills that affect the majority of people. It's worth your time to having a passing understanding of the major concepts.
