chivalry: outdated?

[nerve]

the other day I was with a girl friend and one of her guy friends. she was taking us somewhere in her car and her friend took out a CD to put in, and he said "there is one track on here that you guys don't need to hear. it is for men's ears only." (to clarify something: he thought I was a girl and I didn't feel like saying anything. transsexual. blah.) he was a really, really nice guy. and the world needs more men like him. I'm just wondering if maybe he's a little too nice. I felt his comment was refreshingly chivalrous, but, at the same time, derogatory. I think men censoring themselves in the presence of women is basically treating them like children. if I were a woman, it would really annoy me, but I'm not so I guess I can't say. thoughts? [edit]: ok I think the title is a little misleading, I don't mean chivalry in it's entirety is outdated, just that extreme of it.
