its literally what the germans had to do with the nuremberg laws. its alsways unusual how this is taken as an unreasonable question when its never been answered. in previous white nationalist forums they adopted the one drop rule meaning if you have any admixture at all you are not white. this is not what the germans adopted though. as well in south africa for a time they had courts to decide if you were white or not. so yes if being white was a requirement of have rights in a white nationalist state then they would have to legally decide what that is. you could imagine someone who is somewhat mixed being found to be not white and he fights this in court. a judge or jury would have to decide if he is white or not.
