Making HN worse while criticizing it seems incongruent and doesn't help anything. We've banned that account (an obvious troll: https://news.ycombinator.com/threads?id=ijiiijji1). Meanwhile this other offtopicness just adds noise, and supercilious noise to boot. If you're going to judge a site by the trolls it gets, every site is worthless.
Depends on what you consider to be worse, I guess. On reddit you get many of the blatant fucks. The 4chan memers, the blatant racists, the unabashedly sexist incels. They all know who they are, what they're doing, and they practically do it for fun.
On hn, you seem to have the same demographics, but they either have no idea about what they're actually saying or they're smart enough to argue that it's okay and sound like they've almost made a legitimate argument.
