(What if you're a Native American who live in the U.S.?)Would you punish the children for the actions of the parent/grandparent in any other situation? If you still say yes, and you live in the U.S,. then you need to pack your bags and leave, because your ancestors took the country from the Native Americans.
So because European settlers took the land away from Native Americans, today's Americans can't oppose the institutionalised racism in Israel, the "Jewish State"? Can't call for fairness for the millions of displaced Palestinians and their descendants living in refugee camps? Native Americans are at least citizens of the US and have the same rights as any other citizen.
