The rising interest in cohousing among millenials is probably a realization that white flight is not a financially viable option for many of. They seek community, which requires homogeneity, but cannot afford expensive suburban white/Asian areas that produce high social capital living.
Cohousing is an admirable alternative given the current unlivable
situation produced by diversity and low IQ high violence immigration
corroding formally stable neighborhoods, schools, and institutions.
Christians should be at the vanguard of this movement because we have
a non-racial (i.e. socially acceptable excuse) to create an exclusive
in-group cohousing community.
