Most #socialmedia is a bad way to infer generalizations. Social media tends to show you what you want to see & things similar to what you've seen, which can lead to an echo chamber effect, I think.
When it seems to me that something 'happens a lot' and is controversial I like to check online for statistics.

The #Fediverse has much less "algorithm" but nonetheless you can still get yourself in an echo chamber if you choose the wrong server (e.g. with prejudiced bans on other servers).
