A tyrant can steal everything from you, except the knowledge of who you are. That alone you can give up.
When someone puts you in prison or enslaves you, you still know who you are - even if you are forbidden to express it.
When one makes it one's life's goal to be someone one is not, or to be part of a people one is not, that is total surrender. There is no greater captivity, because one's essence and being have been locked in a dark cell.
It's the worst kind of oppression, but also the easiest to escape. After all, you put yourself there. So, what's stopping you from getting out?
