Being a girl sucks. We have to deal with periods making us a bitch, shaving our legs everyday, and worrying about what we eat.
Hmm, are you sure that's all there is to being a woman? I bet there's a lot of great things you're not thinking about.
I'm just making a joke, so relax, it's not sexist.
I think saying that women are bitches is a sexist thing to say. I also think that most women would be offended by hearing those types of things. Just try to imagine someone saying these rude things about your mother or sister and how it would make them feel.
That's easy for you to say.
Why would you think it is easy for me to say? Most people would agree that you shouldn't make jokes about menustrating women since that's a very difficult time for most females.
