Supremacy is a kind of addiction to feeling superior to a certain type of person or group.
Despite the harm to oneself and to society, innumerable people cannot seem to give it up — do not even want to, in fact.
Being a bully gives one “hits of supremacy” — instead of committing to the hard work of personal growth and levelling oneself up, a supremacist chooses to “elevate” themselves by pushing other groups down.
It’s lazy; it’s cheap; and it goes against the concepts of equality and fairness which are the bedrock of democracy. It’s also unfounded, based on flimsy pseudoscientific “evidence” and superstition wielded through decades and centuries. Supremacy is a convenient self-serving myth used by the ruling classes and races throughout history to cheat others of equal birthright.
