great changers focus so purely on the matter at hand that they do not let their causes get dragged down by insults or violence. Mahatma Gandhi and Martin Luther King, Jr come to mind.

ps - "I don't apologize for that, nor do I regret it." a little humility goes a long way. defensiveness and pigheadedness are quite different from intention and stance. passion is different than fighting everyone. making friends and spreading passion might even be more effective.
