Things were already pretty violent in th South pre-Fall. Form the Wikipedia article on Reconstruction:
An explosion of violence accompanied the campaign for the
Mississippi's 1875 election, in which Red Shirts and Democratic rifle
clubs, operating in the open and without disguise, threatened or shot
enough Republicans to decide the election for the Democrats.
Republican Governor
Adelbert Ames asked Grant for federal troops
to fight back; Grant initially refused, saying public opinion was "tired
out" of the perpetual troubles in the South. Ames fled the state as
the Democrats took over Mississippi.
[73]
This was not the end of the violence, however, as the campaigns
and elections of 1876 were marked by additional murders and attacks
on Republicans in Louisiana, North and South Carolina, and Florida. In
South Carolina the campaign season of 1876 was marked by
murderous outbreaks and fraud against freedmen. Red Shirts paraded
with arms behind Democratic candidates; they killed blacks in the
Hamburg and
Ellenton SC massacres; and one historian estimated
150 blacks were killed in the weeks before the 1876 election across
South Carolina. Red Shirts prevented almost all black voting in two
majority-black counties.
[74] The Red Shirts were also active in North
Carolina.
Maybe what we see Post-Fall is a Turtledovian Southern Fascism
