The rhetorical move of accusing someone of being "brainwashed" as a way of dismissing their beliefs, commitments, or arguments without engagement. The accusation positions the target as incapable of independent thought, their views as mere programming. The fallacy lies in using the accusation as a refutation—as if demonstrating that someone is brainwashed (which you haven't actually demonstrated) proves their views are false. But even brainwashed people can hold true beliefs; the source doesn't determine truth. The accusation functions to avoid engagement by pathologizing the believer.
"I explained why I find meaning in my religious community. Response: 'You've just been brainwashed since childhood.' That's You-Are-Brainwashed Fallacy—dismissing my actual reasons by attacking my capacity for reason. Maybe I have thought critically; maybe my commitments are examined. The accusation lets you feel superior without having to engage a single thing I said."
