Baltimore is completely segregated which makes it easily one of the best case studies for white nationalism.
If you look at the nigger infested areas to the north then yes: you see board ups, drug dealing, chimp outs.
Head south in Baltimore and there is a natural chokepoint that almost no niggers ever cross and I'm telling you it's paradise. The streets are clean, there are neighborhood get togethers, community trust. It's one of the most staggering contrasts in the world.
You can take someone on a 1 mile trip and show them what black, mexican, and white neighborhoods are like. Call it a 5 minute race realist ride.
