I appreciate the clarification that your stance isn't gender-critical, as someone whose life was completely changed for the better by the simple act of putting the correct hormone into my brain.
It's such an incredibly difficult thing to balance both societally and linguistically: that, indeed, there is a concept of brain and chemistry and biological sex and holistic health that really does need to be re-calibrated for some of us, personally and privately - but also that this absolutely essential acknowledgement and/or transitional change should NOT be used to define or police one's expression.
I like to say that gender expression is a social construct, but gender identity - which means (for me at least), what place on the physical and biochemical sex spectrum my brain's wiring requires - is absolutely not a social construct.
Nice writing!
