My perception of the sentiment expressed here is that people are disinterested in inauthentic expression, lack of empathy, or an unwillingness to entertain other people's ideas or opinions.

Mine is that is what people do on the Internet, and it's compounded by the anonymity the Internet provides. Doesn't really matter what platform.

Even in the public open side like Twitter, people just shout stupid one liners at each other, like there's some universe where people changed their mind about something because you called them stupid in the world's most creative way.

The more people you put together, the more colamity. Lemmy of just very new, so maybe the riffraff hasn't shown up yet?
