“then it turned out they are more likely to kill than heal.”
This is not true.
“He bought the line that this is a hard to catch plague (meaning lockdowns would be effective),”
This is not correct. If it is hard to catch, lockdowns are not needed. Just wash your hands be a bit careful and you’ll be fine.
“it turns out to be easy to catch (meaning lockdowns won’t help much)”
Again, This is not true (and I can’t make sense of it, I assume there is a typo. If it is hard to catch there is no reason for lockdown. It is BECAUSE it is so easy to catch that lockdowns were needed. )
“, is closer to the annual flu that kills thousands ever year”
This isnt true . For example last year 34,000 died from the flu in the Us Covid 19 has so far killed 87,000 (thats more than 34,000) and this is IN ADDITION to flu deaths.
“Trump may be a fool”
This is true
