You don’t shout back because you think you’ll change the oppressors’ mind.
You shout back for those who can’t.
Theres an anarchist group at my old university that has been relentless in protesting/shaming nazis and other bigots at the school as well as the school for not doing anything about their behavior. Toward the end of the year some professors told them that they were able to pressure the administration to hire a full-time diversity officer instead of the inexperienced part time diversity officer they currently have as a result of the protests. Shaming tactics help more institutional types by demonstrating that there is a need to be fulfilled and shifting the Overton window in that direction.
