"Sex and the City"? Makes me want to shoot myself in the head to make it stop. I hate that show with a passion.
Just me speculating here, but I'll bet the more feminine women tend toward "Sex and the City." The typical female stereotype obsessed with buying a million pairs of shoes and wearing frilly dresses and pampered princess mentalities. The "girly" girls, as it were. The chick lit genre was meant for these girls.
Then you get the geek tomboys who were almost never into the "girly" stuff as kids. I've been in fandom in some way, shape or form, for as long as I can remember, and I have yet to meet women in fandom who are into the "girly" girl stuff. I'm sure they're probably out there, but my experience is that they're few and far between.
Ironically, I'm a guy and I think I like Sex & the City more than most of my female friends do. In fact most of them wouldn't touch it with a 10ft. pole. Actually, neither would I at first. I only happened to catch some of it while my mother was watching it. I was surprised to discover that it's really good. The superficial materialism may be what originally got it headlines but at its core it's a genuine, earnest exploration of human emotions and the often confusing ways in which we treat each other.
You want something too girly? Try Charmed. It doesn't bother me that the women are the main characters. What bothers me is that the men are so poorly written. It's like the writers are only imagining fantasy men and have never met an actual man in their lives. The men are so poorly written, the show would be better off if it just didn't have any men at all.
My friend Brenda loves Charmed, Doctor Who, Stargate, & Disney princesses but has never seen Red Dwarf or Sex & the City. She's pretty girly but with a heavy sci-fi background. She's read more literary science fiction than anyone I know.
My friend Tracy is slightly more the standard sci-fi tomboy geek. She likes The Hitchhiker's Guide to the Galaxy, Star Trek, and is probably one of the few women on the planet who loves Monty Python. But there seems to be something about Red Dwarf that she finds off-putting. Maybe it's the fearless sexual humor. Something like Sex & the City would probably make her eyeballs explode.
how do I convert my female friends and get them to love this show as much as I do?
Show them a lot of scenes with Kochanski?
I don't think that would work. Firstly, I don't think you'll find a single Dwarfer of any gender who will recommend Series VII & VIII as the best the show has to offer. Secondly, I think gags like the "Have a fantastic period!" sign from "Only the Good..." will just end up being counter-productive.
