I use Sync, you can filter key words in any combination of post content, titles, community names and comments.
It won’t catch everything, but it clears out enough that I get enough other content to keep me happy. You could also block the specific communities for politics.
I don’t keep them in the fridge, I’ve got my own hens and I didn’t before when I got shop bought eggs. I have 0 concern about salmonella or anything like that.
The fridge egg holder is for keeping hard boiled eggs, not raw ones.
