I think it's fascinating that every single instance of this argument, in this and related threads, posters conveniently decide to begin tracing the chain of events that lead to the firing at the tweet--not the jokes.
Not trying to be a jerk - if you feel the jokes are somehow unique or offensive. Most people just don't see it that way though.
I personally am not offended by the joke nor do I think they are clever or unique, but saying that they don't matter because they're the status quo is a really weak argument and it speaks to the lack of progressive thought in this community when it comes to diversity.
The tone of conversations between other males often repels me, but the reaction to calling them out for it is worse often then simply putting up with it, as Adria Richards is experiencing. The focus is shifted to examining the complainant rather than truly evaluating the matter at hand. It's extremely unfortunate to witness or experience and is undeniably regressive in my opinion.
