Just read. Listen. The arguments from both angles are in mainstream media a fair bit.
See what you think.
I mean to me it's obvious that the gender > sex way is. Illogical (words and arguments changing every 5 mins and often contradictory), obviously a big risk for women and girls. And that leaving the female half of the world population with no words to define as one group with distinct needs issues oppression etc etc is an out and out attack on all women and girls full stop.
There's a thread called break it down. On here. Sure someone will link soon!
