I'd chalk it up a lot more to population migration / economic trends than anything else. There are a lot more Democrats who used to live in now-Republican enclaves and have since cut ties with them than vice-versa. i.e. people who grew up in rural areas, went to college, then moved to cities upon graduation. In this election, much of the Republican vote came from places "left behind", whether you want to read that as "ignored to rot by the elite" or "disastrously clinging to a past that will never come back" depends on who you ascribe agency to / sympathize with, but I'd argue much of the "unfriending" is caught up in that storyline.
