The corn-fuzion about having TRA around men only versus having the TRA around women and life is understandable. A man, a truly confident man, deals with other men in a men-only situation somewhat like he deals with people in general. However, in men-only situations, it is necessary to establish your dominance first. That is, to be seen as the leader, you have to deal with the challenges to your dominant position first. This is the way of the wolf pack, the hunter-gathers, the clan, the tribe, the gang, the team, the platoon, the corporation.
MEN are different when there are only men around.
That is a minor point. It just is one aspect of the world. When I use TRA, I mean it toward and around women, even though it would be about the same in an all male group with the above exception. All men with TRA are assertive. TRA is in how you walk, talk, stand, sit, look, gesture, etc.
