I mean, it depends. I am not my own gender police, I don't see my life with my peers as "shaping the culture of manhood" because having gender in common is basically irrelevant and there is absolute no sense of belonging for me into "manhood" as a gender. We are not talking about contributing to shape the culture of your organization, or club or something, where there are (or should be) some form of shared values.

In fact, I find this whole idea between silly and sexist, where by sexist I mean rigid attributes applied based on gender.

The way I see it is that I - as a man - have absolutely nothing to do to help with the overall problem and the only way that I can help improve is by not being part of it (in this case, not assault, rape, stalk, harass etc.). That's pretty much the end of it.
