ANY ideology is intrinsically authoritarian.
Left alone, most people don't care much about how the world or their society works. It takes either a gifted charismatic leader or a force, to make them move in some direction. In most cases, it works sequentially - first the charismatic (may be just well-marketed) leader, then (when they notice that something is wrong) the force.
When I was a kid, our own society (Bulgaria, 1980s) was already used to the fact that something is wrong, but as the technological progress nearly surpassed the social degradation, things were considered acceptable. Almost. It was, of course, pretty bad compared to other countries around, but it was rarely compared (few people traveledtravelled and they were cherry-picked). The charisma of the leaders was long gone, the economy went down and down and the force was gradually applied wider and wider.
