I'll bite on your requirement for healthy masculinity, even knowing this will be an insufficient explanation and open to manipulation given your starting point.
For me a healthily masculine man is:
- Someone who accepts the responsibility of his life
So that means, he doesn't shy away from the responsibility of children, and is fair in how he conducts himself here (i.e. not a tyrant, not a weakling either)
- Someone who will take on some level of risk and/or danger
It's easy to say we don't need men, but if you have ever been in a situation such as an intruder in your house, a masculine man is able to take this on. This is not to say he is a sadist or a masochist, but he has a level of aggression which is controlled and put to use when is required. He is also not a coward.
- He is able to create and be innovative and takes time to be curious and 'knowing'
That means he does have some interest in knowledge and 'becoming wise and reflective and knowing' which helps in all aspects of life. However, unhealthy masculinity in this aspect looks like manipulation.
- Capacity to love
Again, there are unhealthy aspects to this trait of masculiniy showing as obessive love etc.
That is what a masculine man looks like to me, and he may enjoy opera, ballet and have long blond hair. None of that is relevant
