So at what age do you tell the transgender girl that she is too biologically superior and needs to go play with boys? What if her genetic makeup is inferior and she is not even a good athlete?
Virtually every sports organization decided a long time ago what the answer is to your question. Most decided that winning a kiddie sport is just not important compared to inclusion and doing one's party to create a tolerant and safe environment for all children, and that trans girls can therefore play for as long as they're age eligible. The NCAA has set their standard. The NWSL has set it's standard. The Olympics has set its standard. Most HS organizations have set their standards. Obviously club soccer organizations have set their standards. And if/when they decide the standard doesn't appear to be appropriate or working, they change it to address that as the NCAA recently did with swimming, just as every organization does with respect to any issue from time to time.
Your problem is that you simply refuse to accept the very simple concept that winning and losing in youth sports is not important compared to inclusivity, taking action to protect trans children from the inevitable abuse and hostility that they face, and helping educate others to overcome their irrational transphobic fears, all of which you have proven quite clearly is very necessary. And you refuse to accept the fact that pretty much every sports organization around already did this many years ago. In reality, you just don't give a shit about the health, safety and welfare of trans children.
Honestly, there is no point in having a real conversation with you until you are willing to admit and accept the reality that a trans girl is very likely to face terrible abuse and suffering if they are left with the bullshit Hobson's choice of having to play on a boys team or stop playing sports altogether when they're just 10 years old, and that you're perfectly ok with that. It's clear that you can't even muster the ability to admit that transphobic children face terrible abuse from their male peers in sport, because that would require you to have sympathy for a group that you obviously hold in contempt but aren't willing to come out and say. So instead, you make up bullshit excuses about how a 10 year old trans girl is a "safety issue", although that is a ridiculous, asinine position that was rightfully rejected by pretty much every youth soccer organization on the planet many years ago. So then you pivot to "rules are rules" and point to a bunch of rules that actually say nothing to say about the issue and, in fact, which are completely contrary to their actual positions on transgender play given they all clearly allow it. So then, you point to an NWSL policy for professional adult athletes that you want to apply to freakin' children, because you mistakenly believe supports your hatred of trans children. But, go figure, it turns out even that policy says the opposite of what you want because virtually all 10 year old boys fall far below the max testosterone standards set fort therein. So then you claim trans children should not be allowed to play because it's not appropriate to "fuck with testosterone levels", which is also a bs argument because it isn't necessary given that at least pre-pubescent boys fall under the NWSL's limits, which you previously claimed was "gospel".
So what is your next excuse? I know you don't want to go down the road of admitting that you're worried that you and your child's fragile ego can't handle the possibility she isn't good enough to compete with a 10 year old trans girl. I know you don't want to go down the road of admitting that your own fragile self esteem depends greatly on whether your 10 year old daughter wins a soccer trophy. I know you don't want to just come out and say "god says trans children shouldn't play soccer". I know you don't want to claim that you're worried that your daughter playing with a trans girl will educate her that trans people aren't bad and will cause her to question your transphobic views and/or your religion? So what is it going to be this time?
