LH - You were originally talking about 'moral superiority', and now you're not - there are many ways to feel superior, and sometimes it just can't be helped. Some of us don't like feeling superior just for the sake of it, but to be able to bestow a bit of knowledge or wisdom to someone can be no different to giving a gift. Naturally, the motivation can vary, but it's cynical to assume everyone's is as you describe. Having said that, as a Northern English certified curmudgeon, it's my patriotic duty to admire your cynicism ;-)

Don - When are you emigrating to England?
