Suppose the vast majority of White Americans choose White Nationalist leaders to run the country and as a result civil liberties and the constitution were changed to reflect a Christian fascist ideology and laws were enacted that made it legal to suppress non-White Christian communities. Would people still be ok with it because the will of the majority demands it?
Majoritarian rule is a bad thing because the majority will oppress the minority . Look at what happened in Egypt with Muhammed Mursi : as soon as he won, he started rigging the government with Islamists . But I don't support Sisi either because he is an authoritarian.
