Twitter and X were often compared to a global town square. Imagine you hear a rumor on a town square, but decide not to spread it. You can just do that in reality. This is practically impossible with most social networks. That leads to the fact that click-bait dominates so many social networks. That is toxic in my opinion.
There is a growing number of people that seem to be uncomfortable with the idea that people might not share their opinion. This is not a sign of extremism of the others, as it is often stated, but a sign of a healthy and diverse pool of opinions. One can agree with a post and disagree, neither is bad per se or even toxic.
