We have an old saying here, "Winter keeps the riff-raff out."
Subzero temperatures place a limit on the homeless population; they either get it together (with ample opportunities to do so), survive on limited opportunities via charity, or pull stakes and head south.
But the tentacles of policy extend beyond high population areas, like the questionable habits of haute coture or even more simple popular convention, spread by mass media and 'social' media.
This is the battleground, not the polls nor the courts.
If conservative ideas are to prevail, they must be sold in the marketplaces of common thought, namely by 'influencers' in the social media arena.
The entire rural culture needs to be wrapped up like a Madison Avenue gimmick and presented to the new arrivals, many of whom will not see the fallacies and inappropriateness of more urban habits, but will try to impose the errors of those ways on their new venues.
To which I can only say: "RESIST!".
With every fiber of your being, defend the rural culture, even as apartment blocks go up, as new housing sprouts from the land, defend the concept of being self-sufficient, of knowing and helping your neighbors when they are in need, of honesty, of doing for yourself and each other, hands on.
Stay friendly, tear down the divisions which urban pundits have erected in the minds of people, and the red states will gain people, without the poisonous idealogies that have made the areas they fled unlivable.
