If people want to treat me badly for where I live, why should I give them any tourist money? I'm perfectly comfortable in the US (and nobody has been like that in Canada either where I visit frequently). I'm certainly not going to suck up to them by pretending to be Canadian.
I am still wondering what the general outcome will be of the new isolationist politics of the US. The world will keep moving on, with the US as a global power and without it. I fear the world will be worse when the US stops being a global power, but we will see (the US itself will obviously be worse off, though).
