Here's a summary:
Be nice to newbies. Everyone was a newbie once, even you.
Correct!
Assume good faith. If you were wrong, no harm done. If you assume bad
faith and you were wrong, lots of harm done.
Correct!
Admins are so entrenched in their elitist jargon and pet policies that
they forget how to interact with anyone who doesn't know the jargon and the policies.
Just about. I'd only add that admins also seem to love making up new policies or personal policies on the spot, or assigning harsher punishments for behavior that's one of their pet peeves (even though punishment isn't supposed to be the goal of our blocking ability in the first place), or generally treat the newbs like dirt because they know that the newbs won't know the proper ways to respond and try to report them for it, and even if they do get reported, it'll be hushed up because the admins are "longtime respected users" who are "fighting vandals" and we are "short on admins."
We need a welcome bot.
Why a bot? The new user creation script could easily just have a segment added to make the welcome message automagically appear on the user's new talk page, and then flag the new account for "new message waiting."
