Of course you can't censor lies automatically. Toxicity doesn't have a technical solution.
Maybe. Maybe not. If you choose to educate yourself about financial scams, and are always wary when strangers call you, that's sensible given the world we live in. If you see pensioners being scammed out of their life savings and support doing nothing because "I would never let that happen to me, they should take responsibility like I do" that's naieve at best and maybe cruel.
Similarly, a society full of media which insults and swears at people because "people should toughen up" is like refusing to clean dogshit off the streets because people should just wear shoes. Great, now you have people trampling dogshit everywhere, what a success.
Like, yes you should lock the door of your house when you go out. But isn't it interesting that there are places where people don't have to? Wouldn't that be ... nice? Better? Do we really want to encourage a society full of people who are wary, calloused, defensive, always on edge, because doing something about it would be 'weak'?
Absolutely, YES! People should be resilient against words and name-calling -- "Sticks and stones" is a common nursery rhyme for a reason.
