Twitter was always a cesspool, and regardless of if the majority of opinions are left or right leaning, it's a toxic environment no matter who is at the head of the hydra.
Prior to the Musk takeover it was a leftist echo chamber, and there was all kinds of witch hunting and cancellations based on groupthink.
I don't think either extremes should be given a platform, and all I see on Twitter is that Musk leveled the playing field so that both sides get to shout as much vitriol as they want.
