ITT: Americans judging the rest of the world by standards forged in their own racist history. I think you can forgive someone the ignorance of your history and calmly educate rather than just call her a racist or a "fucking idiot". I wonder how much your average American knows about Lithuania? Because I can tell you I know fuck-all about it - a quick check of Wikipedia is telling me there's 264 African immigrants in Lithuania so I'm guessing their black population is pretty low and their ability to navigate racial sensitivities or knowledge of racial relations is probably pretty fucking slim.
It's not a coincidence that this stuff keeps happening in countries with low racial diversity. If we're going to hold them up to our own standards there's gonna need to be a little understanding of their history, too.
But there are plenty of people in here trying to calmly educate, and I don't doubt there were people trying to do the same directly to her. I don't expect everyone to have perfect knowledge of everything, but it is a huge pain in the ass and makes me feel like I shouldn't have bothered when people keep using their location as an excuse when they've been told why it's not ok. If it's posted publicly on our increasingly globalized internet, you're going to get viewpoints from different types of people. Mostly it's frustrating being told to calmly, politely and unemotionally as possible tiptoe over someone else's feelings and take them by the hand and guide them through a minefield, and the other person just doubles down, makes excuses, and tries to ignore the explanations.
