> His strategy worked because it existed alongside MANY other voices, IMO the most underrated of which is Malcolm X, that rejected this "gradualism" outright and refused endless delay.
I have read very many people claim this and exactly zero reasons provided by them why I should believe it is true.
It seems to me like basic common nature that if you see proponents of a cause behaving in a manner you find objectionable, that will naturally bias you against the cause. And I have, repeatedly, across a period of many years, observed myself to become less sympathetic to multiple causes specifically because I can see that their proponents use violence in spreading their message.
I've tried very many times to explain the above to actual proponents of causes behaving in manners I found objectionable (but only on the Internet, for fear of physical safety) and the responses have all been either incoherent or just verbally abusive.
> making it credible that there is a world where those "peaceful" people do not accept complicity or "no" for an answer.
This would only make sense if social change required action specifically from people in power, who in turn must necessarily act against their best interest to effect it.
If that were true, there would be no real motivation to try nonviolence at all, except perhaps to try to conserve the resources used to do violence.
> You cannot have nonviolence unless violence is a credible threat from a game-theory perspective
First, no, that makes no sense. If that were true, formal debate would never occur and nobody would ever actually try to convince anyone of anything in good faith. The premise is flawed from the beginning; you cannot apply game theory here because you cannot even establish that clearly defined "players" exist. Nor is there a well-defined "payoff matrix", at all. The point of nonviolent protest is to make the protested party reconsider what is actually at stake.
Second, in practice, violence is never actually reserved as a credible threat in these actions; it happens concurrently with attempts at nonviolence and agitators give no credible reason why it should stop if their demands are met. In fact, it very often comes across that the apparent demands are only a starting point and that ceding to them will only embolden the violent.
