Margaret Mead said this quote

A great deal of what I say just leaves me open, I suppose, to a vast amount of misunderstanding. A great deal of what I say is based on an assumption which I hold and don’t always state. You know my fury about people is based precisely on the fact that I consider them to be responsible, moral creatures who so often do not act that way. But I am not surprised when they do. I am not that wretched a pessimist, and I wouldn’t sound the way I sound if I did not expect what I expect from human beings, if I didn’t have some ultimate faith and love, faith in them and love for them. You see, I am a human being too, and I have no right to stand in judgment of the world as though I am not a part of it. What I am demanding of other people is what I am demanding of myself.'- James Baldwin
