I think part of it at least is reaching a critical mass.

Lemmy was definitely a collection of relatively like-minded geeks at the start. Even when we disagreed on issues, we all agreed that we needed to work together to make the community grow.

Now that it’s grown to a respectable size, there are more dissenting opinions as well as less tolerance for dissent; and more to the point, there is space for absolutely vile content that used to get choked out. Now to stop this sort of thing, the ‘old-timers’ are more likely to say "shut the fuck up, sit the fuck down, and behave!!!’ before they can get a solid foot hold.

Meanwhile, the worst of those people are feeling both entitled and persecuted, and shouting their garbage louder than ever.

This happens everywhere that gets to a certain size. I remember when reddit stopped feeling like a secret community and more like a warehouse.

Of course, there are other reasons that people have mentioned below: The world is tired, worn out, and PISSED OFF at the half that disagree with them. The president of the United States has broken every rule of diplomacy, grace, and civility that people tended to follow in social life. Social Media has made it far easier (too easy) to dehumanize people and turn them into a one-dimensional pastiche of their posted opinions.

And we’re facing the destruction of the planet, genocide, and the global resurrection of fascism.

The world is getting worse, I’m afraid. I really wish it wasn’t true and I spent a lot of time emphasizing the good to my mom before she died; but honestly, it’s getting worse.
