For fauci/the cdc:

• The whole mask are useless lie is probably the big one.
• There's also the immediate dismissal of lab leak theories.
• Continuing to recommend cloth masks after studies showed they were either useless or became saturated and may exacerbate spread.

For state actions:

• Lockdowns were never part of the recommended approach, that wasn't a scientific recommendation.
• There were the arbitrary rules like wearing a mask in a restaurant unless you were sitting that had no science behind them.
• There were rules like no motorized boats, but non motorized is acceptable.
• Closing schools despite most experts citing the long term affects harming development, also little evidence that kids were at any significant risk from covid.
• Classifying tents with walls and igloos as outdoors to avoid mask restrictions.
• Keeping mask rules while outdoors for well after it was established there's basically 0 chance of outdoor spread for covid.

More generally:

• The obsession with surface cleaning despite evidence for surface transmission being nearly impossible being established very early.
• Criticizing anti mask protests for not being safe, but completely ignoring the same issue with blm protests.
• the overwhelming save all lives at all costs advocacy, which isn't even policy in normal times.
