Established left parties and radical movements fundamentally disagree over whether institutional participation legitimizes rule.

Evidence

On a personal level, Haddad became increasingly annoyed with the MPL. They did not respect the differences between politicians, he felt; they lumped him in with the conservative repressive apparatus he fought against as a young dissident and was now trying to sabotage his administration. He did not believe he was trying to co-opt anybody; the PT was deeply proud of the mechanisms it had developed over the decades to involve social movements in decision-making and bring the streets into the halls of power. These kids were not only refusing to play by the rules, they were pretending that the rules didn’t exist. — Vincent Bevins, If We Burn, 375

• DEEPTHINKING: The chasm where each side’s deepest political virtue reads as the other’s deepest betrayal — PT’s proudest innovation (institutionalizing movements) is precisely what MPL regards as the corruption of protest. Refuses the easy villain narrative.
