How does Martin Luther King Jr. defend his actions?

My favorite quote from the speech is one in which King cites "legal actions" that were atrocities, and the way in which it was "illegal" to stop the atrocities. I love hos perspective.... he point is dead on.

We should never forget that everything Adolf Hitler did in Germany was "legal" and everything the Hungarian freedom fighters did in Hungary was "illegal." It was "illegal" to aid and comfort a Jew in Hitler's Germany. Even so, I am sure that, had I lived in Germany at the time, I would have aided and comforted my Jewish brothers. If today I lived in a Communist country where certain principles dear to the Christian faith are suppressed, I would openly advocate disobeying that country's antireligious laws.
