I think you have to understand biology in order to understand gender fluidity. And then maybe get out in the world more. And maybe just be grateful your chromosomes are standard issue.
"understand biology" Ok then.
Does a trans woman go to a gynocologist? Does a trans male get their prostate checked? Or is this all based on how they're "feeling"?
When a "gender fluid" person goes missing, how does one fill out the description without using race or gender for appearance?
Answer these questions and I'd be on board with the idea. He, She, or It. Pick one.
I'm suspecting this is becoming one of those issues people use to "stand out" from the masses.
