You have a pretty defeatist understanding of the term "workable."

you’re implying violence is required to shift the overton window to the left.

I never implied anything of the sort.

I forthrightly state out loud that the use of force is absolutely necessary to move anything left.

While I agree that waiting for the death of the last generation guarantees movement forward,

Agree? With whom? I never said I buy into this esoteric and ageist liberal claptrap of blaming everything on older people.

the most harmonious option

Fuck harmony.
