From the example you gave, you haven't experienced it either. And the reason I haven't experienced it is because, as the DM, I didn't throw Bahamut at a problem player and just warned them to either cut it out or be kicked from the game. The game then improved for everyone remaining.

Hold on... If I leave the shit pit, I won't be invited back into the shit pit? And that's a bad thing?

You wanna know why I'm so passionate? Because you're infuriating. Because you're writing entire essays about things nobody has been talking about and calling ME passionate about it. Because "rip out the role playing" isn't something anyone has mentioned directly or otherwise. Because everyone keeps replying to me without responding to me. Nobody has explained why it's good to remain in the shit pit for a second longer than absolutely necessary.

If you're in a pit and it's full of shit, either remove the shit or leave the shit pit. I don't get why that's controversial to say.
