If it isn't an issue for you, then you may be a statistical outlier. It seems to be a pretty typical experience for most women -- not all, of course, but it appears to be quite common. Even female founders* sometimes talk about the degree to which they have been treated like nothing but a piece of ass by men they were trying to make deals with, an issue men do not typically have to face when they are trying to launch a business.

For some reason, "observant" women keep denying it though.
Hint: if you were relevant, you wouldn't need to remind people. And if you weren't stuck up, you'd have made a point here instead of acting sanctimonious.
The ones that might interest you most are The Gray Zone, Oh My God It's a Girl! and Glass Walls.
I also put some of the responsibility on women, which gets me into endless hot water and accused of "victim blaming." The post Nothing But a Bunch of Boobs takes that angle (but, then, so does Oh My God It's A Girl!, but it is a tad less controversial).
Do you have ideas how we could reduce this Problem in the future?
