When I grew up, I was taught that if someone in your friend group makes a racist joke, you should stand up to them, and inform them that casual racism leads to normalizing racism.

Even if "Kill All Men" was just a shibboleth of a specific online culture, it seems like objecting to it would be a kind of moral duty (for the same reasons), as long we are in agreement that normalized misandry is bad. But again, in my generation I don't think there was any kind of consensus that misandry is wrong. That's why objecting to a shibboleth like this would be evidence of how "oblivious" and behind the times you are

Okay but "some people are racist and we should stand up to them" is different from "the sentiment that forms of masculinity are some of the chief evils of society was the dominant narrative."

Both are damaging and shouldn't be normalized, for similar reasons.
