When a guy is raving like a lunatic and clearly having a hard time, would use not just put him in a time out, stop his episode progressively getting worse, and making himself look out to lunch. Surly after the 3rd rant on page like 11 or 12 which use could see clearly grumpy was not in a good state off mind, just giving him a 24 hour timeout would've just helped him. It wasn't even banter at that stage was a guy clearly having a mental breakdown..I don't understand why you left him to keep spouting progressively more bile on a thread which was nothing to do with his rants..
