Oh, I was just listening to a story on NPR about something similar, the show Bojack Horseman and how the writers like to put in these little background gags - there was a gag with a dog licking a cop, and the person animating it decided to make it women and everyone was like “NOOOOO!!! That’s gross!!!” And she stood by her guns. But what was reallly sad was that she had to actually put extra thought into the whole thing - making background characters or little site gags like that with women instead of men - her instincts were to default to men. So it’s not like it’s just guys who do this - women do it too, default to men… as you point out, we have similar thought processes about race, too. It’s seriously kind of fucked up if you think about it.
