"We should never let support blind us, or become a substitute for continuing to be both self-critical, and dedicated to our goals. We should not be dissuaded by our critics, but we should be able to honestly ask ourselves if there is anything to learn from them. Hopefully, the fact that sympathizers and critics are taking notice means that we are actually doing something."
