Constructive criticism and self-criticism are extremely important for any revolutionary organization. Without them, people tend to drown in their mistakes, not learn from them.
Being a victim of oppression in the United States is not enough to make you revolutionary, just as dropping out of your mother's womb is not enough to make you human. People who are full of hate and anger against their oppressors or who only see Us versus Them can make a rebellion but not a revolution. The oppressed internalize the values of the oppressor. Therefore, any group that achieve power, no matter how oppressed, is not going to act differently from their oppressors as long as they have not confronted the values that they have internalized and consciously adopted different values.
Oh, if only I could tell someone about my pain and misery! Even myself! Perhaps if I could tell myself about it in some new way it might have the power to shed some light on what had happened and on what would become of me.
All truly wise thoughts have been thoughts already thousands of times; but to make them truly ours, we must think them over again honestly, till they take root in our personal experience.
