The entire list is counter-examples, even the ones they mentioned. I am guessing that they simply disagree with the definition given by Wikipedia. They seem to be claiming that violence prior to a revolution by somebody else who wasn’t part of the party that came into power, but which weakened the authority, is disqualifying as a nonviolent revolution.

If they don’t like Wikipedia’s definition, then they can mention that. But it’s impossible to argue against a premise that they didn’t even specify. They didn’t give substantive anything to argue against, so what would I even be arguing? Like I said, unless they state their specific problem, in my view, the entire list, even the ones they mentioned, are what you’d call counter-examples. They haven’t given a better definition of a nonviolent revolution.

If you want an example where there was no violence at all by anybody, even unrelated parties, and again, the list is only 7 entries long, just look at the June Democratic Struggle, which is the fourth in the list. Two after they stopped looking further, and I think 4 more than you looked at.
