John Stuart Mill provides a classic defense of individual and group rights to liberty with respect to purely private or self-regarding matters: The only part of the conduct of any one, for which he is amenable to society, is that which concerns others. In the part which merely concerns himself … directly, and in the first instance, … his independence is, of right, absolute.… From this liberty of each individual, follows the liberty, within the same limits, of combination among individuals; (...) freedom to unite, for any purpose not involving harm to others: the persons combining being supposed to be of full age, and not forced or deceived.
