"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." - it is impossible to measure the qualifiers "quality", "nuanced", "tolerant", "original", "non-ideological" while still being objective. Thus, whatever implementation for enforcing these qualifiers you choose, it will inevitably lean towards some ideology. Hence, contradiction.
