i dont agree, and i think ur jumping to conclusions.
the way i interpret this rule (tbh i have never seen it myself, just ppl talk abt it) , is that it is in place to stop players not truly representing a 'marginalized gender' from competing, and i can elaborate
there was a player, who truly didnt represent as such, and played in game changers. 'keenc' was a gc player who was basically faking being non binary (the way i understood the story)
he still had to join a team with women, and the women in the team had to accept playing with him. idk much about the team dynamic, but i imagine it took some work and effort
if this rule WASNT in place, keenc could just grab some friends and they could all say they are non binary, despite them not feeling that way truly. keenc wouldnt have to find people to play with. he and his friends could just play in gc without having to put any effort, as the real transgender players do
this isnt the confirmed reason, but i do believe that this rule helps prevent people like keenc from playing in game changers, making it way more difficult to find and join a team
