Believe me, I hate nazis/fascist of any kind, but also think that:

• it is ridiculous to think that every Greek or Roman statue is a fascist dogwisthle;
• the collapse of Roman empire is far more nuanced that good/bad, I do not argue that it was bad yet it cannot be defended that it was simply good: what came after was Dark Ages named as such not by an accident;
• why the analogy might be seen as poor, I don't know how talking about AI (maybe somewhat overhyped) dangers of multiple dimensions is actually an advertisement of AI
