It's only chauvinistic when it is done to gain advantage or with the assumption that acting in a chivalrous way means that you are owed something--or when you insist on doing it when the woman makes it clear she is not interested. For example, I once dated a man who insisted on walking me to my front door from the car (when I presented as female), and he insisted on doing it even when I said that he didn't need to. He then went on and on about how he believed in chivalry, with an implication that it made him a better person and he should be appreciated for it. Well, guess what? I had made it clear that I wanted to walk that twenty feet BY MYSELF, and he LOST points by not taking into consideration my wishes. On the other hand, if he had offered and I said yes, he walked me to the door, and it was never mentioned again... THAT would be real chivalry. But there are too many guys out there who only act chivalrous because they think it will make them look like good guys, instead of doing it because the are sincerely good guys who care about and respect others.
