Repressive institutions are imposed upon us. They need to be explained away. The free society should need no apologists. Those who query its practicability are saying that certain repressive institutions are essential. Most, however, would agree we could do without some of the organs of repression, though there may be disagreement about which of them are dispensable.
Many political reformers wish to abolish some part of the unfree system.
Republicans find the monarchy unnecessary. Secularists want to abolish the Church. Pacifists oppose the armed Forces. Communists object to the apparatus of economic exploitation, at least, when it is not based upon the State. Cromwell dispensed with the legislature.
