The statement "men do worse here because of patriarchal social norms that ultimately end up hurting them" doesn't imply men are responsible for their own misfortune; this seems to misunderstand how society affects its members. In the context of violent crime, an example hypothesis would be that boys are taught by their families, movies, etc. that violence is a valuable part of being male, and because of this social norm, more men end up committing violent crimes. It seems crazy to suggest that a man affected by these cultural norms could have chosen to be brought up in a different environment; I don't know that people are suggesting this when they claim that patriarchal social norms are a problem.
