OK. Let's start from the beginning. The post you are replying to was a reply to the general tenor of a lot of posts, like yours, in this kind of thread. Posts which try to deny that there's a real problem, that the only reason that there aren't as many women in tech is that they have chosen not to.
Anecdotes like the original article, as well as many others that have come before, demonstrate that there is a real problem. There is some seriously problematic behavior out there. Now, how much of the gender disparity in tech is due to these kinds of problems, and how much is due to simple self-selection? That's hard to say; there may be arguments either way. But that doesn't really matter; even if the entire gender disparity can't be explained by odious behavior, at least some of it can, because there are very clearly women who are being off-put by very obnoxious, sexist behavior.
And furthermore, people are offput by defensive behavior, where tons of people come out of the woodwork and deny that there is any problem whatsoever. If you mention that some behavior makes you uncomfortable, and then a lot of people come out saying "there's no problem. It shouldn't make you uncomfortable. You just aren't all that into tech, you don't have thick enough skin" is that going to make you feel welcome and safe?
He's saying that we need to stop being defensive about it, stop trying to deny that problem, and start taking responsibility for hostile and off-putting behavior. Taking responsibility can include not doing it ourselves, and can also include not treating it as if it's acceptable behavior, not turning a blind eye to it, and not denying that that it actually exists.
So by telling him that he was discussing imaginary problems, you were doing exactly that. You were ignoring the actual, real, live example of the problem in the original post, and saying that what he was talking about is imaginary. That's why I brought up the original post; in order to claim that RyanMcGreal's problems were imaginary, you must be claiming that the original post is imaginary.
Now, in other posts, you seem to be trying to make the distinction between bullying and sexism, brushing this off as mere bullying. What you've missed is that it can be both. There is racist bullying. There is homophobic bullying. There is sexist bullying. There is bullying just for the sake of bullying. Just because it's also bullying, doesn't mean that it's not sexist, and part of the pattern of behavior that drives some women from the field.
Taking responsibility does not mean saying "oh, I'm an oppressor, thus I should be ashamed of myself." It means speaking up when you hear someone being harassed, it means stopping bullying that's going on right in your classroom (and being aware enough of your classroom to notice it going on), it means trying to understand why someone's upset or offended and try to think of reasonable, fair ways to fix that, rather than immediately jumping to the conclusion that the problem they are describing is not actually a problem.
> There is a strong correlation between increased freedom to choose "non-traditional" professions and fewer people choosing them. More women worked "men's jobs" when they were told they were men's jobs than they do now that they are encouraged to seek those jobs.
So, where is your evidence to back up this claim? It's a pretty strong claim, so you had better have some pretty good evidence to back it up.
