Political correctness doesn't change us, it shuts us up.

The line frames “political correctness” not as a force that improves people’s beliefs or behavior, but as a social mechanism that discourages speaking at all. Its contrast—“doesn’t change us” versus “it shuts us up”—suggests that enforced norms may produce outward compliance without inward persuasion, replacing dialogue with self-censorship. In this view, the cost is not merely hurt feelings avoided, but the narrowing of public debate and the hardening of private convictions that go unchallenged. The quote fits a broader free-speech critique: that moral or ideological pressure can function like coercion, incentivizing silence rather than genuine understanding or reform.
