I find it especially aggravating when non-US posters scold US voters for planning to vote for Biden.
Look, I get it. Biden sucks. I hate him too. But the alternative this year is Literally Hitler, But Worse. I can assure everyone that allowing Trump to win will be far worse for the USA and the world than anything Biden might do. We do not want a Fascist USA Global Superpower, and that is what we will very likely get with Trump.
Maybe these posters have a voting system and coalition-based Parliament where they live, where they’d be justified in writing off a candidate like Biden. But here in the USA, our voting system is rigged and unforgiving, and we must vote accordingly.
I might also note that telling Biden voters to vote 3rd Party is also a well-known technique used by Republicans and foreign disinformation sources to secure a win for Trump. These posters are inadvertently playing into their hands. https://progressivecafe.social/@TonyStark/111755995729739680
