Okay, so Kristen Stewart cheats on her boyfriend, who she is not married to, not engaged to, has no real legal bond to, and her career suffers. This is not the first movie she has been rumored to be dropped from. (I think it might be the third) People have talked about how this might hurt Breaking Dawn. How people will harass her at premieres or public appearances. Pretty much, the cheating scandal has made her such a liability that it might be a really long time before producers are willing to cast her in anything.
Meanwhile, Chris Brown physically assaults his girlfriend. There are pictures of what he did to Rihanna. There is a detailed police report saying exactly what he did. And has his career suffered at all? His most recent albums have only gotten more and more popular, he won a Grammy, he was invited to perform at the Grammys, and he still has a huge fan base, mostly female, disturbingly enough.
Meanwhile, Charlie Sheen physically assaults his wife, again, with detailed police reports. He makes anti-Semetic remarks about his boss. He goes on a bender that is captured by every major news outlet. And it’s all a joke. He trademarks all the crazy shit he says and makes money off the merchandise. He not only gets a new TV show, but it is the highest rated show on FX.
A+ sexism there, Hollywood.
