As said in the second post:
I see Jack more as being openhearted and sensitive to everyone around him. As I understand him, all he wanted was a little bit of kindness, some sign of loving affection from the men in his life (his father, Mr. Aguirre, Ennis, Jimbo, Mr. Newsome), but he never received any, except for the little bit from Ennis on the mountain and during their reunion. Jack's personality centered and hinged on this prospect of love and kindness. If you notice in the film, Jack was never afraid to show kindness. And I think we can suspect that he learned that from his mother, as his father didn't seem to show him any and none of the other men that he encountered in the film did either.
There are some people in this world whose beings center around this perception of being loved. And I think Jack was one of those people. He pursued many "interests" such as rodeoing and ranching, but I think all in all, these were attempts to be recognized and loved by his father specifically. He wanted to make him proud so that his father would finally show some appreciation to him. Most of the men in his life seemed to avoid doing that.

May I say that sure reveals much about Jack and others !! Does Jack do so, because he is a gay homosexual or bisexual man), and , therfore, is openhearted and sensitive to everyone around him... as you say and others could say too ??
More details ?
