There is, maybe, a solution though I don't like it. For a while now Seattle (really, King County) has been experimenting with (social engineering with) relatively small tent cities for the homeless. They are not concentration camps, though there are some restrictions, and right now they're moving every few months -- often a church offers some land -- but they're highly controversial: almost nobody wants one near them.
Yet, if one created hundreds or thousands of such in cities across the country, mixing these with local homeless, you at least dilute the NO group.
Maybe dispersal into small tent cities would work. I don't know. I know that the Church needs to get cracking fast and get missionaries into those tent cities. It may be a huge evangelical opportunity. There are many lost souls in the NO underclass that need-a-savin'. Maybe the change will open a lot of hearts to the truth. But they need to hear it.
