This is a great article worth reading. http://everydayfeminism.com/2013/10/you-call-me-a-bitch/
Here is an excerpt: “[As for] that woman in our office that we don’t like, why don’t we like her? Is she rude? Is she arrogant? Is she loud? Before we start whispering at the water cooler about what a bitch she is, it’s worth a minute to ponder what we’d say of a man behaving the same way. Obnoxious is as obnoxious does, but we don’t expect men to be polite (though we all should be), and we don’t expect them to be self-deprecating or meek. Are we punishing her for her annoying behavior, or are we punishing her because she’s annoying and female?”
