I think the argument to make space for them is more practical than compassionate. WTF are we going to do if we just refuse to speak to or have any dealings with 1/3 of the working age population. Are we relocating all Trump voters South of Virginia and splitting the Union here?
Setting aside our own authoritarian problems for a second, if you want to have a wealthy country that can oppose authoritarian regimes (like China and Russia), you need all 350 million of us. (And you need Europe, India, and democratic Asia on board, perhaps even some middle eastern countries, all people you may have philosophical differences with that you have to learn to work with).
Sure, but whether you’re talking about military might or economic might, more people is more leverage. That was my point.
