Hell yeah, let the xenophobia flow, boys!
I'm pretty sure you are both American, and I'd trust Xi further than I'd trust your human mutation you have as president right now. I ask again, how do you think USA would respond to two states being cut off by armed guards.
If anything, you should be thanking your lucky stars this is happening in China - so far.
"Woo, some people aren't being seen at the hospital!!111!!"
"Woo, there are problems!!11!"
Right now, China has 2788 patients listed as critical.
Then ask yourself how USA, or any other damned country, would handle that in their over-loaded and under-staffed hospital systems. (The sub-question of which ones are insured is hardly even relevant)
They fumbled the ball at the start, but right now, China should be being praised for doing such an amazing job. They are screening people trying to leave the goddamned place. I don't even need to ask you how that would go down in the land of the free and home of the cowards brave.
Criticism of China right now is pure racist baloney.
