It is not offensive to every woman, you are exaggerating to make your point. Also, it is something many, many men find offensive. In reality. This is a game, though.
Why are you offended by perceived sexism (it's a game, no actual women were mistreated in any way) but okay with other things like the violence? No, I'm not attempting to change the subject I'm merely asking where does this line of thought end? If you take out everything that could offend someone then you are left with Barney Hugs Someone Pretending To Be A Zombie. Nobody wants to play that.
Seriously, please don't expect everyone to agree that removing potentially offensive material is always the best option.
