Nextdoor posts about crime almost always contain a reaction that normalizes it in one horrific way or another. Like if people complain about their car being broken into, someone always says that they should just leave their doors unlocked.

If someone complains about their political signs being stolen it results in someone condemning the content of their stolen sign or complaints like, "yeah but signs on (opposite side of issue) get stolen all the time and you don't see us complaining about it!" So even on the local level it turns into neighbor versus neighbor easily despite careful moderation.
