If someone does try to assert their superiority (I'm trying to think of an example, but am having a hard time) then I tend to appeal to their humanity and ask them to chill the fuck out.
(I don't know of a pecking order on HN. AFAIK you're all my equals. Even PG. He has more money than me, and has more relationships than me, is older as wiser than me, but I don't see him in any way to be my social superior.)
