I think most social justice advocates would agree that corruption and regulatory capture are bad. If anything, I'd expect a response more like "why are women like Yellen and Hillary Clinton being uniquely targeted with these accusations?" (whether they are or aren't). I'm not sure where the parent poster is sourcing the claimed identity-based defenses of her alleged corruption, though.
So the dilemma in the situation you describe is between whether to ignore diversity concerns and in turn be ignored, or to speak up and risk losing class solidarity. It sucks that we have to make that decision; it would be better if less-marginalized people made proactive efforts to ensure we're involved in and will explicitly benefit from initiatives or movements that implicitly aligns with our interests.
