I really hate whenever I try to explain how some bad rules can be abused and immediatelly get someone say shit like "If this happens in your group, change it" as if that would solve the problem. And whenever it is not soemthing you witnessed personally, then it means it never happens and could never happen.
My hypothesis is that a lot of people are emotionally invested in DND, and if you say bad things about it then it feels like you're saying bad things about them. Saying it didn't happen or it was the players fault let's them still feel good about DND.
We're all susceptible to this.
For some reason DND fans seem less likely to just go "yeah it's kind of garbage but I like it"
