This is a week analogy.. french only works as a means of communication because it has internal rules that are objective (as in different people understand the same/very similar thing when hearing/seeing a symbol/word).

Singularity of experience is cool, but anything social requires communication/synchronization.

Even though gender is used as a box or definition people are forced to fit into (and this is bad), reducing human experience to a blackbox kind of singularity is a highly individualist take.

You can work on understanding each other without forcing anyone to fit into your definition..
