Earlier quoted context omitted.
I once heard Big Bang Theory described as "blackface for nerds"* and it made me suddenly realize why I was so uncomfortable watching that show. * I hope no one thinks I'm trying to trivialize blackface which was, of course, far worse than what Big Bang Theory is doing.
I really wish people would stop saying this. Even if you don't mean to trivialize what blackface actually was, that is basically the net effect. It's a terrible analogy on pretty much every level.
I was hoping to not have this debate that invariably comes up about how you can't compare anything to blackface because of how bad blackface was but I don't consider that a valid argument against the comparison.
