They were Knights so it is hardly surprising they mostly male. I really don't understand the need to believe females can be as effective as men in hand to hand combat. Yes the force is an equalizer but the need to push that fantasy goes well beyond this movie.
Sorry you disagree but much like Mad Max in Fury Road the female lead is made more dominant by making the male lead weaker. Finn was little more than a side kick. Same formula as needing to kill off the mentor to allow the student to rise the formula they are using to have dominant female is weak and emotionally damaged supporting male roles. It isn't like even try to hide it, in Fury Roadi the admitted that is what they were doing and the left cheered.
One day the white males in your generation will wake up to the fact that making you weaker is objective of the politics you are buying into.
