I don't think that this is a very reasonable response - making a joke and caring about something are not mutually exclusive.
Comedians regularly make jokes about some of the most abhorrent things that happen in the world. Racism, pedophilia, murder. Do you think that these comics therefore agree with racism, pedophilia and murder? No, of course not. They're making jokes.
It may not have been funny, and it may not have been appropriate (we're not in a comedy club after all), but it doesn't mean esquilax will be OK with "teachers turning a blind eye on students raping other students in detention for not doing their homework".
Basically, calm down, he made a bad joke, it's not the end of the world.
