I think Picard was a good example of positive masculinity. Strong and not a wimp without being overbearing or a bully.
The relationship between masculinity and power is interesting to me. Arguably much of his strength came from his position, and his position came from, as Tapestry argues, taking big risks.
He was also a good example for us budding nerds. His intellectualism was not arrogant or apologetic - so it showed us authenticity and self-respect. His intellectualism also did not give him license to dismiss effective communication, leadership, compassion, or humility. So he showed us how to avoid our worst tendencies.
