They have this already it's called a strict HOA and or a gated country club. The only problem would be is sniffing out the jew.
I have lived in this very situation. The jews are literally your neighbors on all sides. They control the (((HOA))). It is a jew-themed hell. I'm never going back to that.
Good point. I have a relative who bought 25 acres in the middle of nowhere and there's no niggers or jews. A few Californians down the road but they are weary folks too.
