Do not delete your cousins and your racist friends. People of color do not get to delete white supremacy from their life. If you love people or have higher expectations of people, then help them out. call them in and do the work. All the effort you would put into stopping them from doing self-harm and harm to others, use that.If you just toss them away the racist agents of capitalism will get to them. They will exploit and mold them because you disregarded them. Unless it becomes or is an abusive relationship there is not much use in not working out the toxicity from their system.
