Do people really hate the country or just aspects of the government and society? There will be differences of opinion about what is best for it. Most countries have socialist policies around various services that taxes pay for. I think it's fair that the rich subsidise the poor for that to some extent. I'm not against people making a lot of money, but our societies are getting less equal over time. It's almost going back to feudal times.
I pretty much get the impression at least on HIVE and the Discords I hang out that most everyone outside the US hates us.
I don't think it's that simple. There's lots of things about the US I like including some parts of the culture and the landscapes. I've had good experiences there and met a lot of nice people. There have always been issues with the foreign policy and now the current regime is wrecking the reputation of the country. That and the issues some people have getting in are reasons I would not travel there right now.
Some people feel the need to express extreme opinions online. We have more in common than what divides us.
