Have you stopped to think about the implications of what you are saying? If Jim Crow laws were still in force, would you really accuse people who broke those laws of untrustworthiness and poor impulse control? If your answer is 'yes', then shame on you, and I don't trust you. If your answer is 'no', then I would ask you how a desire to smoke a joint is fundamentally different from a desire to sit at the front of the bus. I really think you need to put your argument back on the stove and let it cook a little longer - it ain't done yet.
Thank you for restoring some of my faith in humanity. I swear these just-world-fantasy types want to drag our country in to the dirt.
