Frank absolutely nailed it, some really solid and well-stated analysis.
This is also a really good example of the concerns we have with dunk content here on the site. Like you said, ragebait and dehumanizing discourse but here wrapped in vague leftism and a ton of irony poisoning.
I think a good way of describing the vibe shift in terms of toxicity, meanness, and misanthropy is that Reddit is a 10/10 on the scale of Bad Vibes, but we've got things at about a 6/10 over here.
It's gonna feel bad for everyone immersed in dunking here to look at everything cranked all the way up in comparison, but a frog looking in from outside our 6/10 boiling pot is still gonna see our site culture as toxic, mean, and misanthropic.
