Individual vs community

This discussion focuses on the power of individualism to diminish collective political strategies for change.

So here is the question: How many of us have been in groups committed to social change and undoing social injustice, and felt that within the group we are unheard and invisible? What is the personal balance between being heard and listening? How do you know when you have said too much or are pushing your own agenda? Does anyone have any great ideas for forming community membership that doesn't shut anyone done?
