Radicalis Es Fallacy

A fallacy where someone dismisses all arguments of a person by labeling them "radical," "extremist," or "fringe." The label functions as a dismissal: if you're radical, nothing you say needs engagement. The fallacy lies in treating the label as refutation—as if calling someone radical proves their arguments wrong. But radical doesn't mean false; it means outside the mainstream. The mainstream can be wrong; radicals can be right. The fallacy is particularly insidious because it uses social position as epistemic judgment—confusing marginality with falsity.
"I presented a critique of economic inequality. Response: 'That's just radical leftist nonsense.' That's Radicalis Es Fallacy—dismissing by label, not by argument. Maybe it's radical; maybe it's right. The label doesn't settle it. Calling me radical avoids engaging what I actually said. It's ad hominem by political category."

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."
