For example, crypto is either a new dawn for humanity or it's a useless scam whose only purpose it to destroy the planet. There is no in-between. Same for the vaccine or anything related to politics.
Some websites are better than others of course, but still, I've seen an increasing amount of this kind of extremely polarized opinions even on websites I thought were "safe" from this lack of nuance. Every website is a memetic warzone. It's getting to the point where I'm starting to wonder more and more often whether the person I'm replying to is capable of rational thought or if they're bots, paid actors, or if they're simply unable to understand that there is a reason why "the other side" thinks the way it does (aside from reductive, simple answers).
It's bad. It wasn't like this before, and people being fed custom realities by algorithms was certainly one of the many reasons this is happening.
