There should totally be a movement called “Sleep in Public” where people defend their right to sleep on public property. Sleep in your cars. Sleep on benches. Sleep at the park. Just make it a mundane and regular part of life to see someone napping in the library. It would make it much harder to single out the homeless for harassment if everyone else is doing the same thing and much harder to argue that it’s a “threat to public safety” when it’s so clearly harmless.
