So you say.
And correctly so. Actually as a clarification I should have said “If true they were mistaken” because I doubt that very many southerners believe that they were tyrannized.
In the years leading up to the war 8 of the 15 presidents were southerners. And two of the northerners were doughface’s that sympathized with the south’s Particular Institution.
The majority of congresses were dominated by southern interests. The south enjoyed equal representation in Congress and the Supreme Court.
This is like current-day democrats claiming that they are being tyrannized.
