There's no nationalism involved. It's pointing out that despite being from outside the US, you were one of the leading voices of "both sides are the same" and encouraging people to withhold their vote for Biden. It's pointing out that since there's no consequences for you and anyone you knew, you were okay with a Trump victory to prove a point. Don't play the victim card to hide how selfish you were.
Jumping in here because you and I may have had a similar disagreement.
From my perspective, I feel I only have good intentions for the US. In spite of not being from that country, I care whether or not people anywhere have access to healthcare. Precisely because every other developed country does it.
The only prominent politician I trust (at least as far as I can trust a politician) in the US is Bernie Sanders. Because he has a a trackrecord spaning several decades of turning down big corporate donations. (That's my criteria. It doesn't have to be everyone elses.)
I also agree with him on several issues, in partiucular healthcare and the climate.
Those, along with injustice and unnecesary gun violence, are probably the main issues I speak up on. I wish I could devote as much of my time to every important issue, but I only have so much time in a day, and I have my own country to worry about on top of that.
But from your perspective, perhaps I'm an outsider that wishes harm on the US. I don't know.
I assumed you tought I had good intentions. But the way you reacted to me saying positive things about Bernie, or negative things about other politicians, and seeing your disagreement here with Mnementh (he claims he said one thing, you claim he said/meant another), makes me unsure of that.
In my mind, anyone that geuinely wanted to have Trump replaced with someone a lot less Trump-y, is an ally. Even if we disagree on how to get there.
It's nothing compared to the disagreements I have with people that think police brutality is ok, that don't want universal healthcare because reasons, don't listen to science, etc.
Though for the record, if I was eligable to vote in the US, I would vote for Biden after he became the nominee. He's far from my ideal, but Trump is just extremely dangerous. To the environment, to public health, etc. They're not comparable.
