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.
Considering I've been running 5e since the Plague Year, I wouldn't call myself a hater. I did notice, however, this very pattern whenever I voice concerns about anything with the rules - first people assume whatever flaw or exploit I point out, has been used in my group and then their solution is always to leave the group or kick someone out of it, and if it didn't happen in my group, then it means it doesn't ever happen. It's a catch-22 debating with these people.
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"
As some who argues about the rules a lot, most people know close to nothing about the actual, written rules.
If you do want to debate with someone about the rules, feel free to message me, I enjoy it much more than I should.
