Anaanarchism

 If after we reign in a left Anarchist society there is still god forbid, division , hostility and resentment ,then I would support Pan Secessionism . 

Pan Secessionism would be a unique way to unite persons if the above changes won’t work, see this for more.  .Maybe there would be a human rights model in such a Pan Secessionist society based on this line of thinking on human rights

There would be no deification of “progress” in a universalist context in this Pan Secessionist society

There is a case to be made that targets of hostility, resentment and especially violence would way more easily be able to relocate to escape such hostility, resentment and especially violence in a more localist world (though obviously as mentioned above they ideally should not need to do that)

These include radical localized autonomous zones . As a kid and teen in the 1980s and 1990s, (and to a extremely much lesser extent in in 2007, and in the late 2010s early 2020s) I lived in a radically localized mindset and it was refreshing, liberating and individualistic. It was like I was in my own video game.

It was great as a kid or teen for me not going beyond NJ or knowing any news story save for a handful (i.e fall of the Berlin wall)
