Okay, so not having seen the problems first hand in the chat room, I would still like to suggest that any rule focuses more on disruption than on delusion, as relevant.
If no conversation is taking place except for one person ranting to themselves and the wind, going from one thought to a wildly different one, without interrupting anyone then I think most of us would agree that it's probably not a big deal.
However, if any number of people are having a discussion, especially one on topic to these forums, and someone else jumps in with completely nonsensical or random statements that not only do nothing to add to the discussion, but even distract people away from the main discussion, then certainly I think the disruption should or could be properly handled with a warning then a kick then a ban, skipping any steps as necessary, as normal. Regardless of whether the person is diagnosed with a mental illness/incapacity or not.
Sometimes people, like myself, are just in a random mood, and if I, without any sort of delusional thinking or diagnosis, start disrupting an otherwise good conversation by throwing in random statements (or bash quotes
) then I should be warned and then silenced so as to not disturb the conversation.
I'm all for adding a rule against "disrupting a good conversation with utter nonsense". It's just the word delusion that I am wary of, as conversations can be derailed by non-delusions as well. In my opinion, I think that one word needlessly narrows the rule too much in one specific direction.
