no i don't agree with trans competing against female either, but if it's in the rule by that swim meet organizer then unfortunately that's been determined.
but the original post and rebel media made false claims that a 50 year old swimmer swam against pre-teen
that's not accurate, there's a 16 year old and above category (that means everyone older than 16) also there's an open category
16 is not pre-teen
you can go into a washroom and there's stalls to go into change, i've been taking my children swimming at community pools and private pools, and we always change in the stalls not out in the open
