Honour cultures developed in pastoral societies, where your worldly
goods could simply be lifted one night and you would be left with nothing.  It
was important to show your readiness to defend and retaliate with
force.

Scottish immigrants to America may have brought some of this with
them, particularly to the Southern States!

But as civil society developed and the rule of law became something
reliable, duels etc began to be seen as brutish.  Perhaps also as
democracy matured, with less social stratification?  A dignity culture
developed instead, where insults and slights were considered not
worthy of response, and any actual harm dealt with through the law.

Microaggressions are defined as offensive words or actions that imply a
prejudice, whether conscious or not.  The term appeared in university campuses
with traditionally high levels of tolerance and equality!  Examples are
then publicized across social media, and authorities are challenged to
respond.  The ease of broadcasting the issue and drawing a response
seems to be driving this new type of culture, that
makes victimhood a virtue.

Equality and oppression seem to be particular moral concerns in these environments, more so than others eg laziness, greed.

Overstratification is where the level of inequality is increased in a
social relationship.  Compare highly unequal societies, where the
inequality is often accepted even by the oppressed!

The clash between dignity and victimhood seems set to continue in settings
where actual harm is rare.
