This sort of thing is unfortunately very common in many large bureaucracies, especially across the government. A notable (and likely controversial) case in point is teachers who (sexually or physically) abuse students, and are kept on the payrolls, often in ‘rubber-rooms’. Are public schools worth having?
I don't think many teachers think that abusing students is part of their job, but there are LOTS of cops who think that abusing their power to kill / maim / steal from / rape citizens is JUST fine.
Police killed about 1200 people last year, with 118 happening during a wellness check, 116 during a traffic stop, and an additional 213 for unspecified non-violent offenses.
Only 10 officers were charged with a crime from these cases. What do the 'rubber-room' stats look like?
I guess the equivalent here is the teachers and the teachers unions covering up that abuse, moving the abuses around to other schools, and lobbying for special protection for those abusers even after they are caught and convicted.
Its not perfect as an analogy since police are the state's sanctioned violence and teachers are not, nor are teachers in charge of preventing rape generally, but it kind of works since kids generally do have to go to school of some kind.
I expect in the above hypothetical the person you're asking would agree that yes, all teachers are part of the rape problem. The logic is the same and it hinges on the idea that allowing and intentionally enabling <very bad abuse if power> instead of fighting to expose and stop it makes you part of that problem even if you aren't directly doing the bad thing. Doubly so if your job is to expose and stop that abuse in every group except your own.
