Agreed. Part of that is the 'hot take' represented by the limited characters of a tweet are inimical to nuance. So much of it is just people taking turns 'dunking' on each other, and it gets increasingly heated and rage inducing. Add to that an inflammatory algorithm, where outrage drives interaction, and of course you have a cesspit.
Part of the good thing about the old internet is when you have to construct a blog to share your thoughts, you have to be driven to actually, y'know, build something. It also has the added benefit of being relatively closed off. Now everyone has easy access to an empty field with which to yell into the void... and it turns out with that low bar and high inter-connectedness comes a lot of yelling.
