Feedback is best received when you relate to the person who is giving it and you trust the giver has your best interest at heart.
While the "current environment" may make it so women are more weary of men (and thus less likely to receive feedback) - I think there is a stronger current.
White male investors see people outside of their social group and realize that their advice might not be well received- not because of a flame war, but simply because they don't look like them. I'm fully convinced this effect is visible with all mixes of social groups (race, gender, religion, national origin, job family).
This effect sucks, and we should be looking for ways to unite ourselves to other people so that we can receive hard advice and also give hard advice.
