No one is born racist.
Racism is taught.
I think it’s important to remember, though, that just because someone tries to teach you these behaviours and actions are okay, doesn’t mean that you’re required to accept it.
You can stand up to unacceptable behaviour, actions and words. You can say that you’re not going to be that person. You can acknowledge that racist behaviour is not acceptable and should not be tolerated, and that while it may be deeply ingrained in our past, it does not need to be a part of our future. You can stop the cycle.
Don’t allow yourself to think that you cannot make change. You can. It sounds cliche and I know I’ve said it before, but the saying rings true: you cannot do all of the good the world needs but the world needs all of the good that you can do.
