The rest of America hasn't "handled" COVID at all, unless "handled" means "pretend it doesn't exist, refuse to do anything, and hope it goes away".

How you can look at the United States, where the virus is growing exponentially in thirty states right now, and say COVID is "handled" is simply baffling to me.

The US isn't close to being the most diverse country in the world: source https://www.pewresearch.org/fact-tank/2013/07/18/the-most-and-least-culturally-diverse-countries-in-the-world/#

Note that the most diverse countries from that article are generally handling COVID much better than the US.

If I hadn't talked with many conservatives, I'd be baffled why you bring an unrelated topic, "diversity," into the conversation, but now I know that "diversity" is a synonym "filthy and disease-ridden non-whites" to a significant portion of Americans.
