Also, if you end up having to announce your take on every "bad" thing that happens, your feed becomes nothing but commentary on the bad takes, almost always identical to everyone else, and you dillute or lose what makes you interesting in the process.

I've seen this in my own feed. Any time some "bad" person is exposed, I'm almost guaranteed to scroll past 30 almost identical takes on it by the same 30 people on my friends list. I click them, and 80% of their feed is just their takes on the daily outrage du jour. I don't really know who they actually are as people anymore, unless this is the entirety of their being now.

So now as a general rule I don't post anything about current events on social media, and stick with things actually about myself. I might make a comment on someone else's post sometimes, but not post about it myself.

I will probably make an exception here or there about climate change, because in my opinion that subject is being way too glossed over by society as a whole and is a much larger and more imminent threat than "this person did a bad thing and we must shun them now".
