I'm not sure how you're defining "Leftist" in this case, but I think regardless it's probably a very limited caricature of Left leaning people. The same kind of caricature that paints everybody on the Right as a bunch of racist, QANON believing, COVID-denying, J6ers.

I don't think there are many people alive who haven't come face-to-face with life's inherent unfairness. The question we should all be asking is, "what can be done about it?" Then we can discuss our ideas and our inevitable disagreements like adults.

Both the Left and the Right are failing to do this.
