Just because something was a fault of ignorance doesn't mean it shouldn't be apologized for. Trust me, having seen enough races who are better at it than we could ever hope to be has been a pretty good lesson in when we, as humans, could stand to learn to suck it up and apologize when we say something we didn't mean.
Such people? You mean people who've tried to cash out? Or people who don't really like me? Answer's yes to both.
