For another interesting aspect about of real-world parallels, I read an interesting discussion of how in the Watchmen universe, when costumed vigilantes became a real aspect of the world, takes of fictional superheroes dropped in popularity
As a consequence of this the way Superman had an effect on the KKK's prominence, basically in the mid 20th century some KKK documents and information were leaked describing their practices, their terminology and their nefarious plans and were used as story points for a Superman story run in how he fought the KKK that ridiculed their terms and ideals which led to a huge negative public reception for the group. In this alternate world, the same didn't happen due to the drop in fiction comic books. Its something to think about considering the alarming state of affairs in OK, in the show.
