Think of it as the political versions of "safe zones". I personally think of them as roach motels.
Which would be fine, if they would keep to themselves. However, they infest the motel and then they spread their filth out to damage everyone and everything else. They are a disease. They have an unrelenting need to control others, so they immediately push their Marxist and Communist ideologies on people who are far away from their infested urban centers. The people “in the sticks” don’t have a voice.
