Yeh, this multi-culturalism & secularity... is, to me, placing the state above our own beliefs and expectations of behaviors. We have an over-class crushing attempts to resolve the problem as they thrive on the confusion.
Totally on board then, it's a kind of wistful, utopian thinking; 'If only everyone was more intelligent, our problems would dissolve'. But, if anything, the potential for differences would multiply exponentially, and game theory remains.
