Excellent idea, make sure that all liberals are safely inside the cities and only those who want to live among us crazies are outside, then cutoff all entry and exit points so we nutcases cannot get into the cities and their children cannot wander out into the countryside and be exposed to us nutcases. That will protect them from us and we won’t have to feel guilty about ruining their lives. I’m all for it.
Mexico will need to be protected from us as well so we’re going to need a wall there too.
