In a multicultural society, common sense gets abolished because it’s a matter of settled inarticulate understandings (a.k.a. “deeply rooted social stereotypes”). Bureaucrats must therefore run everything in accordance with their own form of rationality. There’s nothing to keep the society’s fundamental logic from getting carried to completion, so that’s what happens.
For example: in principle, “inclusiveness” ought to mean that no organization taking part in public life can stand for anything other than the principle of inclusiveness itself. Otherwise it would exclude those whose views differ from those of the organization, contrary to what is now considered a basic point of social morality. An academic institution has finally held as much: the UNC-Wilmington College Republicans have been banned from campus because they wanted to discriminate on grounds of political affiliation.
