I'm afraid I didn't see this response until just now, so it's a bit late, but if you're still following this, I'd love to see some more specific references - I googled "recruiting men in nursing" and I see a ton of stuff about how to try to make nursing seem more appealing to guys, but nothing about accusations that the nursing establishment is hostile to men, certainly nothing similar to what is accused against the tech status-quo on a regular basis.

In particular, most of the links related to nursing seem to be making arguments analogous to the much derided "women aren't interested in tech because the work doesn't appeal to women" theory, arguing that men don't like nursing because the work is not perceived by them as male enough in various ways, not that they have any perceptions of anti-male bias in the nursing community. Quite frankly, I'd reject any such notions, since there is no such general feeling, at least none that I've ever heard, so that's not what's keeping people from walking through the nursing school door in the first place (otherwise, I figure I would have been at least cognizant of such a general perception).

Similarly, I'm skeptical whether tech really has any significant misogynist reputation once we look beyond feminist-in-tech bloggers and male me-too hangers-on - none of the women I know seem to have that impression (though granted, they're from pretty varied and non tech-centric backgrounds), and I certainly have not seen where I've worked.

When I have asked my female friends about their impressions of the computer world, they tend to think that yeah, it's a circle-jerk of forever-alone dorks, but they generally assume that they'd be more welcoming to women and more accepting of them than guys in most fields, not less. When asked why they don't do programming-ish stuff themselves, most have said stuff like "that's for the math geeks", and "I study people, not code" (crank the superiority knob to the max on both of those, btw - when I asked this, I got the definite sense that they thought the subject matter was distinctly below them). Not once have I heard "because I've heard that guys in tech treat women like shit" as an answer, which makes me very suspicious when people point to that as the definitive root cause...
