It’s not enough to decide things by majority vote, said my mother to me in (I’m guessing) about 1967 or 68; there also have to be guarantees that the rights of the minority will be protected.
My mother didn’t have a degree in political science, and she may have just been voicing something that was much in the air in those days of desegregation and anti-war protests; but hers is the best test of effective democracy I’ve heard of so far.
She forgot about the special character of referendums carried out under threat of armed attack, but in those days we were still under the spell of the post-1945 dispensation and thought that we’d found a way to keep fascism from recurring.
How nice it was to be innocent and optimistic in those days!
