Google it. Some of the earliest studies out of China showed single-digit cases of outdoor spread were in April. Prior to that all cases were indoors. It wasn't until the race riots in June that more cases of outdoor spread occurred, and even then a tiny fraction compared to indoor spread. This disease was spread in November 2019, not 2020. By the time it was an American crisis much was known.
You don't. Because without a limiting principal, you always have the "what if" driving you to restrictions. Government's job was never to predict. But the very human desire for a pain free world pushes us to stopping hypothetical problems before they happen. The results are never pain free...
"An effect" is not the same as "effective." They were not effective and preventing spikes, saving the hospitals, or "stopping the spread." Also, 20-30% is selective science. If you put the studies together you get around 17%, which as you pointed out previously, will not have a meaningful effect of a highly transmissible virus.
This is also selective science. We have plenty of research showing why isolation is untenable. Humans just don't do it, and when they closed everything public, people just started meeting in groups at private residences, literally the worst environment for spread. There were also no spread differences noted between countries with differing school policies, indicating that schools were not vectors for spread. Sure, "scientifically" there's going to be some measurable difference, but as I said before, effect ≠ effective. Part of scientific studies is measuring effect, not just on a number but on an outcome. None of the studies indicated that school closures would have a meaningful effect, and Europe actually followed that science. Children didn't stop playing, they didn't start wearing N95 masks properly, and so they didn't stop spreading (insofar as children were spreading the disease, if at all). A scientific study on a hypothetical is sometimes neat, but it doesn't work for policy justification.
On that we agree, but the new definition of compromise from the left is you compromise your position to join mine.
You're guilty of the same breathless posturing. Are you ok with a 5-15% mortality rate? Yeah dude, I am. So lets compromise. States that aren't ok with it lock down. States that are can open up.
The problem with compromise from a political standpoint is that we already have it built it. States' rights was designed specifically to allow for compromise. But the left wants everything dictated from the federal level. That's the antithesis of compromise. But California can't run their lockdown the way they want unless Texas locks down too. Yes... That's the compromise.
