I continue to be confused why social media companies want to censor, and not let users themselves censor content how they want (including with algorithms). This gets around basically all issues for all parties. Basically let me block Nazi content or whatever from my feed, but if someone wants to see it, go ahead. Honestly this would be great, as I could probably block all political posts as well, leading to a better user experience.
