We are against elitism.
The fundamental principle behind antielitism is the notion that even when an elite is vastly more intelligent than a commoner, that commoner still best understands his own interests and circumstances. Thus a commoner is still best suited in pursuing their own interests.
Whenever an elitist takes away a freedom of an individual, they can't claim to be pursing that individuals interest and thus there must be a greater justification for the seizure of said freedom.
The only exception is when said commoner is mentally ill or mentally underdeveloped. Examples would be children and insane people.
