Prejudice is a great time saver. You can form opinions without having to get the facts.

The line is a dry, paradoxical joke: it treats prejudice as if it were an efficiency tool, exposing how bias short-circuits the hard work of inquiry. By calling it a “time saver,” the speaker highlights the temptation to replace evidence with ready-made judgments—opinions formed from habit, stereotype, or convenience rather than observation. The second sentence makes the mechanism explicit: prejudice lets one skip “the facts,” but the implied cost is intellectual laziness and moral error. The wit depends on irony; what seems like a practical advantage is actually a critique of how quickly people can rationalize unfair conclusions.
