Lawn‑signs Undermine Neighbourhood Trust

Public political signs on private property transform neutral shared spaces into ideological markers, making neighbors feel surveilled or unwelcomed and reducing everyday trust and incidental social interaction. This dynamic can escalate after shock events (the author cites post‑October 7th anti‑Zionist signage) when signs shift from expression to threat‑signal among minorities. — Local visible political signalling reshapes civic norms and can accelerate polarization and residential sorting, with consequences for community cooperation, local business climate, and informal public safety.
