> Sure. And that problem is bullying. It has absolutely nothing to do with women in technology. Saying "imaginary problem X is totally real because real problem Y is real" is not logical.
The problem is not bullying alone, though that is part of the problem. Something can be both bullying and sexism at the same time. Bullies will frequently reach for the strongest ammunition they can get, whether it's racist, sexist, homophobic, or any of a number of other ways to hurt their victims.
Just because it's bullying doesn't mean that it's automatically not sexism as well.

Really? A video series called "BranwashingInNorway" about how there are a few people in Norway who are too politically correct to admit that there are some sex-linked behavioral differences?
Did you have any particular evidence for your actual claim that that once it's no longer taboo women don't want to cross traditional gender lines any more that you wanted me to look at, or am I supposed to trawl through the whole four and a half hours?
How about an actual reliable citation in an academic paper, rather than someone who's just trying to demonstrate that there are a few Norwegian academics who are a little too PC for their own good.
> Why don't you need evidence to back up the claim that women are avoiding certain professions because of sexism?
I do. There is plenty of evidence. For instance, the original post that this whole thread is about, though you choose not to believe it, or somehow are trying to classify it as not sexism. But there's plenty more as well:

This is a woman who was terrorized from showing up at tech conferences due to threats of rape and murder.
Or how about this, a compilation of several sexual harassment issues that explain why Valerie Aurora, a Linux Kernel developer, no longer goes to certain hacker cons:

But OK, maybe you'd rather have statistics than anecdotes. How about this study which shows that women are more likely to leave fields which are more heavily male dominated:

That, of course, doesn't address harassment directly, but the general sense of unease that being in a small minority can give you, which can drive you out of the field.
I'm not claiming that the entire gender disparity in tech is due to harassment, or a poisonous atmosphere, or anything of the sort. What I am claiming is that it happens, it does drive some people out, and it's a bad thing. You seem intent on denying that there's any problem whatsoever.
