My relationship with girly things is kind of weird, though it does have things in common with several other previous posters.
First of all, yeah, don’t assume. I hate it when people assume that because I’m female, I like babies, cooking, fashion, shopping, celebrity gossip, jewelry, and chick flicks. I don’t like any of those things. (Well, okay, sometimes I like shopping.) Almost all of my interests go toward the “guy” end of the spectrum, or are gender-neutral. I get along better with guys and geeky women than with “normal” women.
But that’s not to say I have contempt for these things (well, maybe celebrity gossip–it completely escapes me why anyone cares) nor for the people who enjoy them. Everybody’s different. If you want to spend the majority of your time talking about babies or fashion, fine. I’ll be bored stiff. But I’d be just as bored hanging around guys who wanted to talk about nothing but baseball. And you’d be just as bored if I wanted to go on about WoW or video game hardware.
I guess the bottom line for me (this is really kind of a cornerstone of my personality, because I so rarely get to experience it) is that I want people to hold off their assumptions about me before they get to know me. As one poster mentioned upthread, do NOT make a sly comment to my spouse about having to buy me some glittery nothing in order to make up for the technology purchase he makes. Damn it, I’M the one who’s more likely to make the technology purchase, if you’d just get past your blinders long enough to see that female doesn’t necessarily mean “access this set of assumptions and cue this set of responses.” It’s rude, insulting, and just plain bad business. You can treat everybody with neutral courtesy and cheerfulness without making any assumptions about their personality. That’s really all I ask.
Everybody’s different. Some people (women and men both) enjoy fashion, family, sports, auto repairs, flower arranging, and fruity drinks with umbrellas in them. So what? There’s nothing inherently bad, wrong, or inferior about anyone’s favorite pastimes, just because they’re stereotypically feminine or masculine.
The only “girly” pastimes I genuinely do have contempt for are (as I mentioned above), the frothier of the celebrity gossip (things like “OMG! Starlet X was seen in a bikini last week and she has cellulite!”) and outright ditziness (especially if it’s affected to attract men). I value intelligence highly in both genders. Stupid combined with girly turns me right off (just like stupid combined with macho does–although I don’t like smart macho/male chauvinist guys either, so that’s kind of a wash).
