Is looking like Magnum PI still considered masculine? God, I hope so.
I personally prefer both men and women to have a little fighting spirit, and I don't view masculine traits as negatives, unless the individual still has problems controlling his impulses as an adult, and can't manage to be productive with that energy.
"God is the name by which I designate all things which cross my path violently and recklessly, all things which alter my plans and intentions, and change the course of my life, for better or for worse."
