Without systems that promote quality, non-ideological, nuanced, original, tolerant dialogue we will keep running into the false dilemma of unmoderated cess pools or heavy handed moderation.
If we are to avoid this dilemma we need systems that organically promote constructive, tolerant and inclusive communication, and original, nuanced, intelligent, non-ideological ideas, instead of the opposite.
This cannot be done by organizations whose profit incentive is aligned with user attention instead of user satisfaction.
Those organizations benefit from degraded communication until strong moderation is both continually demanded and decried.

On a side note, I am so disappointed in the constant framing of ideas as right or left. It dumbs society down incredibly to view so much through the filter of two (often arbitrarily correlated, historically shifting) clusters of supposedly disjoint options.
In the real world, communes work well sometimes, markets often work better at scale but not for everything, markets require "social solutions" like non-commercial criminal and civil justice systems, education and health could be explicitly tested and then managed as investments with a pay off of lower taxes (including for the rich) instead of as charities forced on the rich, etc.
The Right/Left and associated ideologies are all self-defeating when believed in isolation and the nuances of their ragged edges, their limitations, and constructive combinations ignored.
