Like this ideological extremism?
I'm sure Democrats would do this to Americans if they could.
China is an outlier even compared to most dictatorships, so I'm not sure why you're bringing it up. Democrats already have the U.S. presidency and a majority in Congress, but we haven't seen anything remotely similar to that in the U.S. Aside from the separation of powers that makes it much harder to go to such a length, Chinese society is also markedly different from that of the U.S., and Democrats haven't proposed anything similar to what's taking place in Shanghai.
I think your sureness that Democrats would do such a thing to Americans is misplaced. I know you're opposed to them, but that doesn't mean you need to believe all kinds of hyperbolic assertions about them or their platform.
**** the mask mandates. It's over.
What is over? The pandemic? Current death counts in the U.S. (since we're not talking about other countries too) say otherwise:
United States COVID - Coronavirus Statistics - Worldometer
At least you're vaccinated. There are unvaccinated people who have also opposed mask mandates throughout the pandemic, which basically means they have always wanted life to go on as if nothing were happening despite the above figures.
