What these wide equal opportunity norms require depends on how one should draw the line between public and private spheres.  Institutions established and run by the state are in the public sphere, as are business firms that seek to sell products and services to individuals or to other businesses. A club devoted to playing a sport or promoting a hobby is in the public sphere, as is a league of such clubs. Friendships are in the private sphere. Dating and mating are in the private sphere. Many aspects of family relations involving socializing among family members are in the private sphere. Several friends cooperating together on a project or activity are engaged in private sphere association, but establishing a club or association to promote a general purpose is engaging in the public sphere. The line between public and private for purposes of applying the public sphere equal opportunity norms will no doubt be blurry and indefinite, but that does not per se drain the norms of content or significance.
