The actual solution is to limit your social media use unless you want to be subject to abuse.

I only have my Facebook for friends to contact me via messenger. As well as it's original purpose, commenting on a ( real life )friend's engagement photos with a nice congrats.

The moment you get into stuff The Facebook wasn't designed for; like actually meeting new people, arguing with strangers, etc , then you run into problems.

I have some very strong personal beliefs regarding how I live my life. I don't need to argue them though. I also have various strong political/ societal beliefs. Again no need to argue them.
