Actually, if the RTFM message was not posted as an AM message, I would expect it to get downvoted. Hard.
While the actual message in the post is somewhat correct, the tone and the the illustrating examples are downright rude and demeaning. The RTFM post has a very high risk of getting downvoted, and I guess that was the reason why it was posted as an AM message.
No matter how frustrated one might get at what might be dumb questions or ignorant users, there is absolutely no reason to become unchivalrous. Better for that monk (if he/she indeed has an account) to have not posted that message at all.
