For examples of cultural traditions that violate human rights and considered worthy of change, Crash and I were using Female Genital Mutilation (FGM).
I have individual rights, but I can't do anything I darn well please, even in the privacy of my own home. I cannot beat my girlfriend, I cannot molest children. The same applies to "cultural rights" or "national rights." There are things that cultures or nations are not supposed to do. I would think that it is obvious that FGM would be near the top of the list.
