My son was in wrestling when he was in elementary school. He and I discussed if he were to be set to wrestle a girl (we knew of a couple of teams who had girls on them). Before I even said anything, he stated he would forfeit rather than wrestle a girl. I supported that choice and agreed. From what I recall, some other boys did the same.
Now, I don’t know what would happen if boy said that they would not wrestle a girl. Probably get kicked off the team and suspended from school.
Maybe the insanity will eventually stop when women take back their games.
While coaching soccer (frosh soph in high school) I had three girls who signed up for the team. They practiced hard and there was no girls team for them so I kept them on the bench.
In one game we were so far ahead that I took the starters out and let the bench play. When one of these girls went on the field, the other team walked off.
At the time I was not impressed that they were making a statement, as far as they were concerned, I was humiliating them by beating them so badly, and then letting a girl on the field. (She was by far not good enough to play in a highly competitive situation), but I always did my best to let the second string on the field if we had no way we could lose.
This is not the same thing as a born male proposing to compete in the girls ranks. But it did upset the other coach.
BTW, as an adult, I played in a lot of coed soccer games. I regretted hitting a girl with a strongly kicked ball, and after that I tried to play “nicer” . But I still did not see anything wrong with the coed make up of the team.
Wrestling a girl is a “no win” for the guy. If he wins, “So big deal you beat a girl.”. If he loses, “Ha..Ha.. you got beat by a girl.”
But more fundamentally, I think forfeiting shows respect for the difference in gender and it is the right thing to do.
