Name one instance of "Leftist dogma".

The whole PC Revisionist "it was all about slavery" argument is leftist dogma.

Thank you. I knew that you weren’t up to the challenge. Now go back to your Sunday cartoons...

FLT-bird: "The whole PC Revisionist "it was all about slavery" argument is leftist dogma."

Your "traditional" explanations of "it was all about money & class warfare" is pure Marxism.
The slavery explanation has the benefit of being what Fire Eater secessionists said in 1861, and what Lincoln's Emancipation Proclamation of 1862 was all about.

Very few at the time explained it as pure economics.
