There is some amount of control when you are accepting and possibly celebratory in response to behaviour that should be discouraged.
For example, if you never sexually harass someone yourself, but you are silent while other do so, you are ceding a control that you have over the situation.
If more people that were respected in the community called out these behaviours when they happen, you may see them happen less (though this isn't an absolute control, so they wouldn't go away completely).
At the same time, you can always claim that "the community isnt doing enough" because "enough" and "the community" as so ill defined that you can always castigate "the community".
Somewhat OT, but this is something I wish people could understand about groups like Occupy and GamerGate. The criticisms of both are often measured in such a way that the targets of the criticism can never do "enough".
