Are we actually claiming that "Virus leak from scary china" would've gotten people to wear masks more or isolate more, versus "Virus killing people keeps spreading?" Or am I missing the point?
I think it would have. A huge portion of early deniers (generally people of a conservative disposition) were in the "it's just a flu" camp. I think "scary virus from China" would have made those people stop and think "there's no telling WHAT this thing could do!"
I think you're understanding the point. Consider what you would call an average Trump supporter. Consider what they would think if Trump declared "This China flu isn't a normal flu. The Chinese designed it in a lab and now it's out in the world. I urge every American to wear masks and get vaccinated to stop this Chinese flu."
How do you think the average Trump supporter would respond to that? Now consider what would have happened if he went all out and said the Chinese released it on purpose? It's scary to think that if he pushed the bioweapon angle it's likely that Republicans would have been lining up for vaccines and the other side taking the advice of Jenny McCarthy and refusing it.
There is so much wrong with how the pandemic was handled and the #1 things were making it a political issue, using xenophobia as a reason to not implement effective policies, and not treating it like the medical emergency that it was.
