Steve Sailer identifies a core truth in modern discourse:

Diversity doesn’t mean “diversity,” it means who is good and who is bad. The bad people can’t appeal to some technical mumbo-jumbo about what the word actually means. When we use a word, it means just what we choose it to mean — neither more nor less.

The question is, which is to be master — that’s all.

Once you understand this, so much else makes perfect sense.
