I would think British emergency room doctors have a DAMN good idea how sick a person is. If MP wasn´t prioritized, he simply wasn´t sick enough to warrant it.
Also, believe it or not, some people send follow-up posts to questionable posts of theirs, relativizing their previous outburst ("sorry guys, and I apologize, this was in the heat of the moment."
I believe the only follow-up post MP did was telling a poster "Keep it coming, and you can see how fast I ban you."
