Sexist jokes are not just jokes. They are methods to reiterate the Patriarchal hegemony in our Society. It becomes harmless only if a girl saying a similar joke is treated the same way as a guy is treated, with kid gloves and even with admiration. In a Society in which all the freedom are given to males to say anything to anyone and not to females, such jokes become unpleasant to the oppressed gender. Isolating those who say it loudly that it is unpleasant is another Patriarchal tactic to maintain status quo.
