[You, sidestepping and being coy] Such as? I'm not familiar with the term.
Marxists talk about vanguard-led revolution and wars of liberation as a validator of vanguard (Marxist) leadership. Liberation of the masses washes clean and exalts violence against the bourgeoisie and other oppressor classes, and it validates the despotic power of the visionary leadership and its right to lead policy. McPherson's writing applies that conceptual framework to the Civil War and American society.
You haven't heard of "wars of liberation"? Of vanguardism?
Nope.
