Dense networks of human relations tend to lead to those humans creating specific network topologies in which liberal values tend to emerge. In places where the network is sparsed (relative to elsewhere), it is here we find reduced empathy for distant others, mistrust, populism, higher social distance between any two random nodes overall, and also bastions of socially conservative thought.
My growing belief is that most social conservativism is network damage to the social fabric. But if that sounds slippery, don't worry: there is no need to purge it, as reducing the average path length in the network will see that happen on its own. Pluralistic values and greater ability to form consensus arises in spaces where we re-weave the social fabric into the sorts of topologies that cities tend to permute through on their own.
Be very skeptical due to my lack of citing sources, but I share the above in earnest with this comment left in haste <3
EDIT: to be clear, I believe there is also some "illness" in the progressive left as well, due to their social distance from certain groups as well. The network is sick. A healed network will be some place in between, at a place we can all live with :)
