Flawed ideas can conquer the entire world, and generally they do a good part in ruining it in the process. Think fascism, communism, nazism, various religions. They've all done their part in making the world more miserable with their nonsense ideologies.

Curiously, they all share the same flaw. They all wish to impose their views on others through force (as does anything that is authoritarian). Apparently reason and dialogue are not well-suited for communicating their ideas.

Note that liberalism in the classical sense is the first, and perhaps the only ideology that acknowledged the issues with the use of force.

Look for the use of force anywhere, whether it's physical, intellectual, emotional, mental or otherwise, and you'll find bad ideas.

I don't think there's any way around it. We like our hierarchies and their existence requires some measure of force.
