So what we are going to discover in the first movie set in the past is the first person to feel the force was female, and she was able to commune with it peacefully and that peace existed in the galaxy. Then a male touch it and was turned to the dark side, and that all males were seduced by the dark side and it started an era of conflict and war.
The second movie, we‘ll learn from Ashoka that the force is female, and cannot be used safely by males without falling to the dark side. Mando will ask the obvious question that there is a history of good male Jedi, and here we will get the big shocker reveal. All good male Jedi were either gays or transgendered.
The final movie will be Rey having come by this knowledge, and having teaching women, gays and transgendered how to use the force which will herald a new era of peace in the galaxy.
I may be off on some details, but I think the core concepts will there.
