Turn down the volume. Facebook specially takes "high engagement" content that is politically charged and full of hate and prioritizes it for distribution. They have shown they can deemphasize harmful content around elections, but when the heat is off, they go back to the old way to maximize time spent on platform / ad revenue.

In fact, remove the news feed altogether. It has nothing to do with "connecting the world", it exists only to hook people on low quality / high engagement content and the source of most (but not all) of their problems.
