I remember the vitriol of old reddit. I believe you are contributing to that more than helping.
Reddit was never pure in terms of discussion or kindness; I think you've got some heavily tinted rose glasses on. But reddit succeeded and brought you the deep, insightful discussion you crave because the enthusiasts were there. And enthusiasts are human, they are not all heartless cogs there to infodump and complain. The most knowledgeable, well-read, and well-spoken people I know are also ones to crack jokes and make their passions accessible and interesting.
If you want healthy discussion, I strongly believe you should allow at least a bit of levity and let people speak a little more freely. Chastising people for not being insightful enough will turn away plenty of the people you want to keep.
Let neckbeards and normies mingle. It's okay to have fun.
Also worth mentioning: this is Microblog Memes. It's in the name.
just cuz you graphics drivers ain't installed doesn't mean it's not running
