Yes, absolutely. My one quibble is that I think their point is slightly less valid in that if the men in question got it together to become better humans (and therefore better partners), the imbalance wouldn't be nearly as bad. Partly on the socioeconomic level, because then their companies wouldn't be alienating or excluding so many female employees. But also on the personal level, because somebody from their past might see them as a good catch.

But yes, they should definitely be fighting the system, not getting mad at women and/or society at large. Of course, the whole of incel culture is pretty good at explaining why no woman wants to come near them.
