educate yourself
An instruction to people on the Internet (and occasionally in real life if you're into being slapped) to go away and read unspecified literature until such time as they agree with your point of view entirely.
Example:
Normal person: "Israel isn't racist, men can't be women, curriculums don't need 'decolonizing'"
Critical social justice loon: "educate yourself you fascist"
