Once people did not want to be restricted by their gender. Today it is some form of cult that doesn't allow any dissent. A fate of many with once noble goals if they turn to point their fingers at others.

Exactly. They'll make documentaries about this someday.
If a documentary of our life and times is made it will be of enduring tragedy, hope, and with luck eventual progress in the face of many crisis of substantial nature. It wont be about trivialities like this any more than it will be about how I stubbed my toe this morning or how you got stuck in traffic.
If we need anything at this moment it is perspective.
