The latent suicidality meme should be overwritten with something more positive fun and pro life - whatever you like really (that doesn't interfer with other ethics). Only harming others is business of police and government. Self harm is no business of cops. The natural consequences of it are punishment enough. "Protecting someone from themselves" is also not legitimate. Taking away more freedom and dignity from a person only decreases their will to live. The not immediate but latent and therefore highly infectious suicidality mind virus is a serious extinction threat to humanity (while I again emphasize that there should be no thought police, only individual ethics). Protect human life AND human will to live!
