In fact at one point you're pointing a fanon-like argument back at him without acknowledging it or its original point:
> the societies liberated by such ideologies become unruly as they essentially condone violence as means to an end
Fanon's claims are consistent with this, he addresses it directly. Except he of course is talking about societies that use colonialist violence as a means to their ends, not those reaching for liberation through violence. Seems relevant here. If those who use violence for liberation are corrupted by it, what does it do to those of us who use it for no great purpose except our own benefit, as our societies certainly have?
You're also conflating military conflict with violence per se, an error that Fanon doesn't make. This elision allows you to draw distinctions between resistance and civilians that doesn't exist as we're seeing so so clearly in gaza right now.
And then, finally, this distinction between "good" peaceful nonviolent resistance and "bad" actively violent resistance is ahistorical. None of these groups or figures consistently considered themselves to be divided in this way. Malcolm X and MLK were allies, that disagreed and opposed each other on some issues, and respected and abetted on others. Successful nonviolent resistance movements generally, certainly the two you mention specifically, are effective because of a radical movement with the will to violence at its flank.
White people negotiate with MLK so that Malcolm X doesn't burn their businesses down. Look at the environmentalist movement for what you can accomplish through peaceful protest without the threat of violence behind it: global scale and decades of mobilization accomplishing almost nothing.
