This is a thought experiment, not an actual proposal, so hear me out. Let's take one state (Alabama and Mississippi come to mind as front-runners), and make it white-only. There will be a national relocation service, and within a period of say, two years, all non-white, non-Christian (can't have Muslims or Jews here!) people will have to relocate to anywhere else in the country they want. Similarly, all white supremacists, including KKK, Nazis, "alt-right", etc., will have to relocate to this newly-whitened state. For convenience, let's assume that Alabama is selected, and renamed Alabaster.
Once that is done, it will be illegal to espouse those views outside of the state of Alabaster, but it will be completely legal within. We can follow the Chinese example and create a Great Firewall around Alabaster, so that all social media posts made in this state cannot be seen outside, and posts from non-whites cannot be seen within. Inside Alabaster they will be free to fly Confederate and Nazi flags and erect all the statues to Confederate figures they want. Anyone caught promoting white supremecist messages in the rest of the country will be forced to relocate to Alabaster. And, of course, Fox News will only be able to be seen by residents of Alabaster (and it will be the only news station).
We could also make it more comfortable for these racists by eliminating some of the other things that bug them. Obamacare will not apply to residents of Alabaster, so they can enjoy being excluded for pre-existing conditions and the like. There will also be no federal taxes: income tax, social security, medicare - none. Of course, no federal funds will be given to Alabaster, so they'll have to maintain their own roads, feed their own poor, care for their own elderly, all out of their own pockets. In other words, Tea Party heaven!
Having set the stage for this thought experiment, I'm wondering what the population of Alabaster would eventually be. In other words, how many people in the current USA would volunteer to move to such a white-only state? And for those who did, I wonder how happy they'd be, now that all of the things that they are currently so angry about have been removed from their lives. I would like to hear your thoughts on this.
