Understanding transgenderism.

[Anomalocaris]

Gender is cultural, not biological.  It's a floating variable that contains no specific instructions.  It's not firmware, or any other software.  It's certainly not hardware.  It's certainly not a heritable aspect of a machines architecture.

It's a construct.  Manufactured.  An idea or theory containing multiple various conceptual elements, typically considered to be subject, not empirical.

Gender roles in a society is very likely largely cultural, although it is by no means clear whether there are deeper rooted cognitive or behavioral differences which shape in subtle ways gender roles societies evolve.    If there are, then gender roles are not exclusively cultural.   individual identification with one gender rather than another is also by no means clearly driven mainly by social gender roles.
