The problem isn't maleness - it's a particular cultural expression of maleness. Particular gender roles. It is not masculinity but fragile masculinity that is the problem.
A maleness that is tolerant, and inclusive - that does not think that men who are more feminine are lesser, that does not equate physical strength with virtue, or dominance with achievement is what we need.

In short, we have no use in this society for maleness as long expressed in many cultures. We have need of a new maleness, that celebrates new virtues. We no longer need strong protectors - we need nurturing dads.

Men need to become comfortable being nurturing, emotional, vulnerable - and celebrate that as achievements within each other - because these traits are not in any way 'feminine' - all men have them, we just need to stop suppressing them, and stop advancing a culture that demands their suppression.
