Racism won’t exist if we all just pretend it doesn’t exist and ignore all the ways in which it still does. By pointing it out, you collapse the racism waveform and it suddenly comes into existence. Therefore any racism you may see is entirely your fault.
Similarly, if everyone was just free to use any old words to describe people of a different race, gender, nationality, or sex without repercussions, then those -isms would also disappear. It’s really those darn blacks who take offense to being compared to monkeys that is keeping racism alive and well.
