Hoc Est Radicalismus Fallacy

A fallacy where someone dismisses arguments by labeling them "radical," "extremist," or "fringe." The label functions as social dismissal: if it's radical, it's outside acceptable discourse and doesn't need engagement. The fallacy lies in treating marginality as falsity, ignoring that many truths were once radical and that social position doesn't determine correctness. It's argument from respectability—confusing what's acceptable with what's true.

"I proposed significant structural changes to address inequality. Response: 'That's just radical extremism.' That's Hoc Est Radicalismus Fallacy—using the label as a dismissal, not engaging the proposal. Maybe it's radical; maybe it's what's needed. The label doesn't tell you; thinking does. But labeling avoids thinking."
