As much as I'd like to take credit, we are not why U.S. tourism is struggling.
You have made it clear we are not safe in your country. We are not assured basic human rights like habeus corpus or due process. As a nation, we are insulted, threatened and talked down to, while people just like us are being arrested and deported to concentration camps in a South American dictatorship without a trial and without any time frame or prospect for release. This is a death sentence accomplished by subtler means. You have also made it clear this is all intentional, purposeful, and not going to change. Your hatred and disdain of foreigners is clear. Perhaps some would try to argue that we are the "good" kind of foreigners and thus we should understand that we are safe, but we understand better than you, that if other foreigners are not safe, none of us are safe, and neither are any of you. Nobody sane is going to travel to a country like that for a holiday. At most they are only going to travel there reluctantly and with abundant caution. U.S. policy is why U.S. tourism is struggling.
