> They will reinforce the same strict gender stereotypes
What if they are just voicing their opinions?!?
I had a girlfriend that was very "stereotypical" - I practically had to beg her after every meal no to go to the kitchen to clean up, but to stay with me at the table and just talk and relax. Is she wrong by being who she is, just because she is "reinforcing illogical stereotypes"?
People are different. Be yourself, hang out with people who accept you for who you are. Let other people be.
A valid question but I'm going to make the judgement call and say that opinions that take the form:
"You should not do A because you are a member of group Y and Y's aren't good at or don't do A" are not okay.
Your girlfriend was probably quite satisfied with a kitchen that had been promptly cleaned and that made her happy. However if she ever voiced the opinion, 'You should help me clean up', to your younger sister then that wouldn't seem okay to me.
Basically some other women will often be just as discouraging and as sexist as some men. They will reinforce the same strict gender stereotypes for the same illogical reasons as the men.
