"Tropes" are popular way to explore fiction. The kids love TVtropes. I believe we can hijack the term to remove stigma from the open discussion of so called "race realist" topics.
So instead of saying,
> The nigger stole the bike, because niggers love to steal bikes
You might try,
> The nigger stole the bike, because sadly he fell into the classic trope of Nigger Who Steals Bicycles
It's a People First™ approach to politely discussing politically incorrect facts. Done correctly (not saying nigger), it could penetrate leftist mental defenses.
