I wouldn't say it's a grudge, exactly, but yes a lot of feminists aren't happy with the current "pros and cons" that men and women get. I would be perfectly happy to open my own doors if it meant getting paid a little more, for example! And... would you believe that apparently women in some cultures pee standing up? Fer serious. (Not relevant to your point exactly, but it's an interesting question about just how "natural" the differences between men and women are.

)
As for "pressure" I don't even necessarily mean that it makes you miserable (or bothers you at all) just that there is a certain expectation that men at least
offer to pay, and that can make life difficult for some guys -- I know that some men who can't afford to pay for dates feel embarrassed when their girlfriend pays, and some girls refuse to date a man who isn't able to pay for her meal, and I personally think that's a pity.
I agree that men and women are on average physically different (for starters: uteruses are mostly a lady thing!) but I'm still not convinced about the mental side of things. And I think our culture overemphasizes the differences; sure, men generally have more upper body strength than I do but I'm still physically
capable of opening a door or pulling out my own chair. Sexual dimorphism in humans really isn't
that extreme!
(And about the murder thing... that was totally a joke! I've only ever dated very sweet guys who wouldn't lay a hand on me. But thank you for your concern.
