Racism is cope. The reason why people bother with it is because theyre insecure and it makes them feel better about themselves.
Imagine this, you're an incel and you're white. You dont have the power of a normal white guy because you're ugly as fuck and that means you cant fully reap the benefits of your skin. Women dont want you, and this makes you angry. How are you going to release that anger?
By putting other people down. Can other races be racist? Sure. But who are the people using the word ethnic, nigger, sand nigger, wetback, chink? Who are the people who are constantly slinging JBW and cherry picking random events then categorizing entire races on them?
Who are the people who riding on the success of their ancestors and speaking as if they've done anything relevant in the world. I'll let you figure it out.
