There's really a lot of nuance in the libenstraum plan. The untermench are allowed fair chance to prove their bloodlines and their suffering is minimized while they're allowed to labor in our state of the art labor camps. We can't allow them back into the general population because they've become thirsty for violent revenge which makes them savages that need to be kept in camps.

If only they'd stop being so anti German and accept their position and stop resisting.
