Gotta focus on what you personally have control over. We can’t directly influence the way other people behave, especially those we don’t know. Refocus on how you can help (and be helped by) people in your own community and you will feel much better.

If you’re not sure where to start just do an internet search for “mutual aid [your city/region]” and show up to an in-person event. That should get the ball rolling.

Reddit is a living emblem of the problem this is trying to solve so I have no idea what you mean.

Mods can’t be trusted to enforce the truth. It’s far too complicated and they invariably end up enforcing their own distorted view of the world instead.
