Well, at least you asked.
Yes, the Left has indeed lost its shit. It's sold its soul to stupid, counterproductive ideas that brought about Trumpism. No matter how much some of us tried to warn them, they just had to do it. They allowed their ideology to control their reason, their curiosity, and their very thought processes. As commitment to an ideology usually does.
The Right? What has become of the Right is worse than what has become of the Left, because the Right has (a) exposed some profound sociological problems that have been under the surface and growing for a long time, and (b) literally put our very democracy at existential risk. Definitely worse, and that's why I spend more time on that here.
I have not once, not ever, said the Left and the Right were "equal". I hear that one from both ends, ironically. What I have actually said is that the behaviors of the two ends of the spectrum are spectacularly similar, and I definitely stand by that.
