There is absolutely nothing evil about this.
You people think that you have a right to say "No, I disagree with your political ideology and you shouldn't be allowed to practice it". This person has legitimately purchased property in order to found a community of like-minded individuals to live in.
I seriously wonder that if some commie founded a commune where "private property was prohibited", would you people be screaming at him because "abolition of private property violates the Constitution!!11". No, of course not. You just have double standards because you can't handle that some people do not like blacks and want to spend their life around people of same race.
You people whine if these people live in cities, you people whine if these people try to found their own community. Face it, you just don't like their political ideology even though they've done nothing illegal, and want to force them to abandon it.
Liberal tolerance in progress once again.
