I still don't get why SJWs get so huffy about how "I shouldn't have to educate you!" If you're not willing to justify your argument, why should anyone else take it seriously?

Sure, I get sick to death of explaining the same things over and over to some people too, but if they genuinely don't know something, they're not going to learn it unless someone takes the time to explain. If you're not willing to take that time, that's fine - you're not obligated to. But then you can't reasonably expect anyone to change their minds or behavior.
