I'm glad you're able to do those things. A lot of people talk the talk online without actually living it offline.
That being said, I think "the uniparty" is just another way of saying "both sides bad," a phrase uttered by right-wingers and right-wingers who fancy themselves fence-sitters while exclusively attacking left-wing candidates.
It's a term that sanitizes apalling right-wing behavior while downplaying the work of progressives who take beatings, from "friend" and foe, while trying to accomplish anything that actually helps people.
I've no doubt that I just angered a few tankies by even calling members of "the uniparty" progressives, but as I said they'll call them "genocidal imperialist capitalists" regardless.
