Beware of what?
Although they make very nice friends and neighbors, and appreciate the winters and low taxes, relatively low crime, etc., they read the New York Times and Washington Compost even after they move south, and they vote the same way as they did up north. They will turn your red community blue. I know this is a sterotype, but it is also true.
BTW, I don't normally talk politics with friends and neighbors.
Liberalism is a disease that infects the mind of it’s host and leaves it completely devoid of all rational thought.
Once the infection is complete and the host has destroyed everything around it by draining the resources of those not infected (conservatives) it moves on to a new area to destroy.
They should be eradicated like feral hogs. In reality, shooting a liberal, using their own logic, is nothing more than a late term abortion.
