I've got a relatively high tolerance for this kind of thing. Most of my life, I've been in male-dominated environments. I was an EMT during college, one of three women on the service. My two undergraduate degrees are CS and math, and I was the first female math major to graduate from my college in something like 10 years. There were only two other women in my CS graduating class. And now I'm in the so-called real world, where it's a Very Big Deal Indeed that our last two developer hires in my group were women. This brings the total number of women in my group to 10 (total group size is 60), one of whom is the secretary.

Which is to say that a lot of your examples didn't even hit my radar as sexist. They are, but my bar for when something will register as sexist has been moved so far that they just register as painfully lame jokes that are only slightly more lame than your standard-issue knock-knock jokes. So that said, the one that actually made me say "dude, what a sexist prick" was 33217, since it brings rape into the discussion. That's the line you don't ever cross.

In my life as a professional technical woman, one thing that I make sure I take time to do is to be a mentor. I mentor other women in this crazy company to help them realise that they're not alone, and that they have real technical contributions to make in a geek culture that is rarely accepting of women. We talk about things that I've certainly never talked about with any of my male managers, like how to make the decision of having kids and how that impacts your career, or how to handle it when your male co-workers are referring to every woman they've ever met as "bitches", or how to identify sexism that tips over into something to talk about with HR as opposed to something you just figure out how to deal with.

It's also one of the reasons that I actively maintain my work blog. I rarely talk about issues that are relevant to women in my blog. There are plenty of female bloggers out there who are already covering that ably. My goal is to simply be a blogger that happens to be female, and to be taken seriously as someone who is actively contributing to my fields with my writing. This is about showing that I have a contribution to make, and yes I'm female too.

Hmmm, I have no idea if any of this made any sense. :)
