I absolutely agree with your experience of the Monastery, and I have the same expectation of being called out or corrected when wrong. And I also agree that "It's better to reply with the facts, rather than abuse.
I'd like to say that I don't think anyone intends to be deliberately abusive towards sundialsvc4, but, honestly... I can't. You can't just accidentally log yourself out and post obvious troll replies to him, so the number of AnonyMonks trolling him is a pretty strong argument that some people are deliberately abusive. Which isn't something I mean to endorse, but I do understand where it comes from.
In any case, what I was trying to get at with the line you took issue with was that sundialsvc4's experience of the site is rather different than that of the average poster to the site (new or otherwise). Offhand, I can't think of anyone else that the site is half as hostile towards as it is towards him, so his experience of the site is not a good gauge of its attitude towards new users.
