I'm a millennial. Anecdotally, I haven't seen as much bashing on gen z at least amongst other millennials. The older folks are going on about hair colors and the typical boomer stuff, but I see more acceptance of the youths amongst my peers. Most notably gen z tends to be a lot better with showing emotions and communication. I think the only thing I've complained about is these past trends of kids just ripping sinks and urinals off the walls in bathrooms and other oddly destructive things. That felt like a newer trend that I didn't experience going through school or really hear about.
