I think of feminism as equal pay for equal work, as well as equality in terms of rights. Men and women are equal but not the same. There's a reason why a decent guy will drive you to your door and wait until you're safely inside, or offer to wait with you at the bus stop when it's late.
Biologically we are different, and our social reality reflects this. In the same way that a man wants to look out for you, he should also want to impress you. Chivalry - offering to pay the bill, opening doors, getting you home safely - is one component of that.
We can also look at the financial math of being female. Women pay considerably more for services like haircuts and dry cleaning. And, in keeping with certain pesky social standards, we are compelled to wear some sort of make-up, purchase feminine hygiene products (pretty much non-negotiable), remove hair from large swaths of our bodies, and possess more varied wardrobes than those of men. Many women also feel it necessary to dye and highlight their hair, and spend money on manicures and pedicures (I don't personally spend money this way.) Really, the sky is the limit when it comes to the feminine sex and grooming. Much of this effort is often made to attract a man and end up on that aforementioned date...with someone who can't be bothered to pick up the cheque?
Once the relationship has evolved to a certain point, it's normal and healthy for both partners to pay for things together. But he should still want to impress you and look after you in small - but significant - ways.
What do you think? Guys, do you try to pay for your date, or do you split the cheque? Am I radically off-base here? Girls, does it turn you off if a guy doesn't offer to pay the bill?
