Can you think of an example of pernicious ignorance in social media interaction?
I think on the english-speaking internet specifically, there's a lot of American defaultism- most because of America's disproportionately large population among native-english speaking countries, and the fact that a lot of popular social media sites are American and first got popular in America. I saw this during Covid, when users on Twitter criticized a couple for having a wedding with a big crowd (this was during the American lockdowns)- only for the OP to reveal that she was a New Zealander whose country had safely exited lockdown far quicker than America.
