Well, as a creator, create! Emily is bawdy, risque and fun. She has a perfect delivery and sense of timing and for you to make an issue of her "teenage years" is a desperately simple cheap shot. The standard, predictable, "feminist objections" had no impact because, in a nutshell, nobody got hurt, no one was murdered and many of us got a laugh. I really like her for her ability to juggle risque humor with wit and natural skill.
Just for having used the taboo word, "cunt", isn't a basis for objecting Emily's performance. This kind of objection is, to me, close to superstition where certain sounds we make with our mouths are going to call up demons, invoke gods, make you crazy or somehow corrupt you.
That imbecilic belief that, "no one must ever be offended! Ever!", is and has always been so patently absurd that it only proves that too many things are far too stupid to ever go away but we have to believe they will.
