To quote Captain Picard, 'There comes a time when men of good conscience cannot stand idly by and follow orders'. Watching an innocent be punished for a crime they didn't commit is definitely one of those times. If people like Gandhi & King had taken a step back, then this world would have been a much less noble place. (guess there is more GJ in me than I thought)I agree that being a man is more than ability to procreate and being a woman is more than the ability to breed children. However, If you lose your manhood, you are no longer a man. Regarding Sima Qian, if he can be like 99.9%+ of other Chinese and kept quiet about Li Ling affair, he would not face such tragedy. In life, sometimes to have to take a step back in order to have a great plain and sky for you to enjoy.
We cannot apply modern morals to Ancient times. Remember ZSF was nearly crippled when it was discovered that he had learnt Shaolin arts without permission and he had used the skills to defend them. There is no way Shaolin would have tolerated an entire family using their arts.Sometimes you have to do what you have to do to protect your family. I don't think their any thing wrong for Lin Yuantu to teach his family all those great martial arts to defend themselves from powerful enemies. Again to defend themselves, not for going after other innocent people. I don't think Shaolin would go after them just for being know the martial arts.
