For me in answer to your points, yes really.
My take on the world as being sort of feminist/marxist, with very strong social constructionist perspective, I see cultural rules and therefore rules about normal, as being made up, but made up and enforced by the powerful rather than the majority.
So in my bitter and twisted opinion, the rules which predominate in western world and to a degree elsewhere, are made up by white men to keep in check, women, non whites and to a much lesser extent working class white men.
Examples of the enforcement are religion, not faith mind, but organised religion. This provides very powerful explanations for why the meek should not worry about the unfairness in the physical world as they will get their turn in the next life. Or women have 2 roles to play, the madonna or the *****. Such inventions also have the advantage of utilising the divide and rule mechanism as obNOXious has probably had experince of.
