The complaint about the double-standard has nothing to with whether women are comfortable with the current rough-and-tumble of FOSS discourse; it's about men being uncomfortable with women who are half as outspoken as the men themselves are.
Re: assertiveness, self-promotion, vigorous disagreement: Yeah, I think we're talking at cross-purposes a bit. By assertiveness I mean, for instance, speaking up when one has something to say; there's nothing wrong with pointing out one's accomplishments when relevant (rather than as a way to knock others down); and as for vigorous disagreement, it is entirely possible to present one's thoughts in a forthright manner without attacking anyone's ego. "Thanks for the patch! The current version has a few problems that prevent me applying it as is; could you look over the following and see what you think? ..." All those are, I think, good things.
OTOH, there are some people who delight in turning fact-based disagreements into personal fights, and are happy to win through logical rudeness[1] and gratuitous nastiness. One of the usual ways to pick up social status in geek circles, for instance, is by flaming people to a crisp -- these are scored not on whether you happened to be right or wrong, but on how thoroughly the recipient is ground into dust, and how entertaining bystanders find their destruction. Many communities have designated targets for their members to practice on.
All that is just obnoxious, and goes *way* beyond "vigorous disagreement". Often someone who gets called on such behavior will start waving around terms like "free speech", "healthy debate", "vigorous disagreement", as a way to deflect criticism, but pff. That's just more of the rudeness that got them into the mess in the first place, and I'm under no obligation to buy into their self-serving redefinition :-).
One more point about the idea of raising the bar for men rather than lowering it for women: In addition to my concerns about whether that's an accurate description of what we want, it seems to me that by framing it that way, you run the risk of providing comfort to those who *don't* want to give up the double-standard -- you may give them an excuse to stop worrying about habitual sexism while feeling virtuous about working on the "real problem" (whether they accomplish anything or not). I assume that's not your intention, but the possibility makes me uncomfortable, and might be off-putting to other potential allies as well.
