He's a salesman selling his cult-ish stuff with that, obviously, but he's talking about creating communities similar to how minorities operate in our countries essentially.

The parallel society model is the correct one, if it's spearheaded by a political vehicle with the ultimate aim of each participating community to gain power through that vehicle. If it's just community building as an end rather than a means then it's totally toothless and akin to white flight, 'becoming like the Amish' etc.
