Murray was a great example of how to have a "big tent" without sacrificing your principles. In our current environment, I see the political dividing line as being those who call out regime propaganda vs those who believe/propagate it.
One of Lew's great pieces of advice is that we don't have to resort to our opponents dishonest tactics because "the truth is on our side".
Murray N. Rothbard: A Legacy of Liberty
By Llewellyn H. Rockwell Jr.
"While upholding the radical ideal, Rothbard happily cooperated with anyone who wanted to limit government power, no matter how gradually. The perfect was never the enemy of the good in his mind; the good was always an improvement. He combined idealism with realism, scholarship with accessibility, and boundless curiosity with commitment to truth."
