No one is truly black or white. Where all complex and layered individuals.
Racists/facist are people who hate others.
Hate is the emotion that makes people want to hurt or even kill when given the chance.
Everyone can act racist, even you. Especially when this is normalized in your surroundings you may never even realize it is racist. The majority of such people can be helped with better education making them aware of the suffering that systematic stereotypes cause.
Real racists don’t because they already know. their intention is to hurt. The only way to fix them is with vast therapy.
Personally i am a far left anarchist. No masters, no slaves, no violence and no borders is my ethos. But if i start calling everyone who is simply worried about immigration a fascist then, i am quickly going to end up with no one to collaborate with.
