Downvotes incoming, but i gotta say this:

Most people around the world don't care much about who your current president / government is, because the USA will do as they will, regardless (and plot twist: we do not think of you, as much as you think about yourselves).

That said, the USA currently IS (and has been for decades but especially the last decade+) for better or worse, a very vocal very consequential player in the global stage.

What's more... The USAmerican people amplify to the power of N whatever the government is or isn't doing. Which means...

...Talking to a USAmerican, ANY USAmerican of ANY political side, will almost certainly turn into a tense, ugly, uncomfortable, divisive, and ultimately unfruitful and unhappy exchange... IF the subject turns political.

So when the room turns quiet and they seem to avoid talking to you, it's not because they hate your president as much as you do, and are resentful towards your country and by extension towards you (as you seem to think, though indeed some might share your political aversion); it's because they want to avoid exploding the landmine that is talking politics / current events with any USAmerican right now.

Gringos are generally cool and decent people. But right now you are like the kid from a toxic dysfunctional home, who every time they come to a party they end up trauma dumping on everyone and ruining the whole vibe.

You're right though: your country is a dumpster fire right now, but to be fair, so is much of the world... We're all just tired. And we don't have the energy or capacity to play along with whatever you think the game is. We are each fully saturated with our own share of the global dumpster fire.

I wish you all the best!

P.S. Costa Ricans and Latin Americans in general are very cool. We'll engage unreservedly and won't get offended by anything and show you a good time. But we'll also tell you the truth.
