The thing about 'not all men' is it's something men bark at people who are lashing out at the group that's hurting them. Trying to separate themselves and remove any affiliation.

All it does is tell those people to shut up while doing nothing to change the structures that allow toxic masculinity to continue that original victimisation. Step in and tell fellow men to stop, that it's not ok, instead of telling people, especially women, you're not like the others so how dare we get angry about it.
