>[!abstract] >The Nazi bar is an internet parable about tolerance thresholds in communities: if even a single Nazi (or extremist) is allowed to remain unchallenged in a bar, soon others will gather, regular patrons will leave, and the bar will effectively become a Nazi bar. The story illustrates how tolerating intolerant actors, even passively, can transform the character of a space by normalizing extremism and driving away those unwilling to share it. It is often invoked in moderation and governance debates as a cautionary principle: to preserve an open, inclusive environment, certain forms of intolerance must be actively excluded. >[!related] >- **North** (upstream): [[Paradox of intolerance]] >- **West** (similar): — >- **East** (different): — >- **South** (downstream): —
