The average post-pubescent boy is stronger/faster than the average post-pubescent girl. Not so much prepubescent. I think this is pretty obvious in wrestling based on the fact that most/all of the girls who have won/placed well at a state high school tournaments have been in the lowest weight classes that tend to be filled with boys who are barely hitting puberty. Also, there are more and more girls winning in lower grade competition against the boys (10-12 y/o and younger)

I don't know what impact puberty blockers have on the strength/speed of the average transgirl vs the average cisgirl. (I am also aware that hormone blockers are not required for an athlete to compete at the hs level as a member of the gender with which they identify).

I think parents should be made aware of the WIAA's (or whatever organization) policy on gender inclusivity/ exclusivity. In the case of WIAA, parents should simply assume every opponent their athlete competes with could be cis or trans.

Anecdotes/ random thoughts
(1) one of my girls is much stronger than many other girls. Assuming I'm referring to a cis girl- do parents need to be told she has a significant strength advantage?
(2) there are nonbinary/ more masculine appearing (assigned female at birth) wrestlers on the girls' teams- I wonder how many of the "biological males" that are "ruining" things just don't look girly enough.
(3)Like many relatively experienced wrestlers, my girls have competed with and trained with boys. So far all the injuries have been the result of training with inexperienced girls.
(4)a few years ago our hs coach made the girls aware that there was (may have been?) a transgirl competing at a meet and if they were uncomfortable wrestling said athlete that the coach was ok if they chose to forfeit.
(5) where is the big fuss about the transboys. I know we have had at least one transboy on a sports team at our school.
