It's weird reading that without context. It's rarely the case, that people sit at home, randomly have an idea about what society should look like and then stubbornly refuse to tell anyone about it. Rather, when people say "it's not my responsibility or duty to educate you" it's usually, because you just were racist or dehumanized queer people or something similar. People who are victims of this shit educate and argue with people all day all their lives, not because they passively would like to see one of their random ideas put into practice, but because it's necessary for their survival. But all this is tiring, even traumatizing. They can't do it every single time someone is being an asshole again. There are just too many assholes. So when they encounter the one too many assholes of the day, that's in my experience the usual time when people in real life sometimes say: "Please educate yourself. Just because I'm queer (or black or muslim or etc.) doesn't mean I'm your unpaid tutor on how to have basic human empathy." And that's valid.
