Yes they do need common ground and understanding. That's the point...

The drive for more diversity for diversity sake is a fools errand and seems more and more like a fantasy to me. The whole point of a a voluntary community is that people would CHOOSE to live near people of like mind. I mean... its really just the idea of nations but on a smaller scale. Its an old idea really. Its also being tried in several places already.

Old examples are the Amish but the private cities movement is more liberty minded example. In many ways we saw this voting with your feet thing happen during Covid as well. The US states are not libertarian but several states have zero income tax.

I think when people talk about anarchism they envision some utopia where everyone is living in a hippie commune. That would exist I'm sure and go up in flames. Most people don't want that including me. But currently people are so limited in their thinking due to only hearing from the Ds and the Rs.
