It's pretty racist (especially the government), but the US is a big place so the answer to your question may vary greatly, even from people living in the same state.
I've met some WS who weren't outspoken about their beliefs, they were "smart" enough to not talk about their views when there would be obivous consequence, i.e work, family, partner, etc. Insidious blighters!
Now, quite frankly, I don't know exactly how the UK or the rest of the world sees the US, so answering that is difficult...
You don't know what they're dealing with, their struggles, their finances, or whatever. It's incredibly rude to record a stranger, make fun of them, and then post it on the internet. Someone needs an attitude adjustment.
