You’re right about exercise. I’d go even farther and say don’t even bother with dedicated exercise if you’re just starting to lose weight, because it’s completely irrelevant to the weight loss part.
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.
