Keep in mind that these attitudes and thoughts you consider racist, took quite some time to develop.
White supremacists frequently claim the same thing — “I didn’t start out a racist, but I became one because of the things that I saw.”
Your statement is just the racial reverse of the position held by Klansmen, Aryan Brotherhood members, and the like. You are an entrenched racist.
People die under every government on earth. Very few black people die because of white supremacist movements. Granted, it does happen, but white people also die because of black supremacist movements. When a black man attacks a white police officer and gets shot, that is not white supremacy. That is personal stupidity.
