We generally assume pretty much all of the Americans we meet in Europe vote Democrat, with the theory that Republicans can't find Europe on a map and wouldn't want to go there if they could.
It's presumably not true, but it makes it easy for any visitor to be accepted.
I was an American in Austria during the first Gulf War, and people were pretty hostile to both me and my wife.
But then, Austria does tend to its own thing.
Europeans tend to understand that it is not your parents fault.
Also, Europeans don't tend to put as much identity in what party you vote for.
I have a lot of US friends, a lot who voted for Trump.
I would never hold any grudge to them.
What I do find insane is the US two party system.
The people who voted for Trump should be held responsible for what they've enabled. This could end with a lot of people dying (e.g. being unprepared for epidemics or cutting off welfare programs).
Plus, it's not like we saw Americans as god's gift to the world prior
No one wants to go on a vacation where they have to deal with unnecessary stress.
It might not be wise to loudly declare yourself American in the EU or Canada right now.
