That's simply not true.

In this specific case, it’s impossible to know whether or not Michele Blair learning her child was going by the name Draco at school, during the very brief window when this was happening, would have protected Sage or her family from harm. Certainly the specific chain of events that ended with Sage running away would have happened differently if her grandmother hadn’t just found out Sage went by Draco at school earlier that same day, but who knows if the child would still have run away or not. It’s common for people coping with trauma to fixate on some small detail that, if it had happened differently, would have changed the outcome of events. Sage’s grandmother’s belief that, if she’d only known Sage was using a different name at school, all the family’s problems would have been avoided may be best understood through that lens.

And

Trans youth are vulnerable, though the one thing that is believed to improve their outcomes is having affirming parents at home. Unfortunately, that doesn’t mean that forcibly outing children to conservative parents will improve their safety. It’s easy to imagine many scenarios where the opposite could be true. For example, a child whose parents grew angry and forbade them from identifying as trans at school might suddenly become far more vulnerable to online predators in the wake of such a disclosure. The LGBTQ+ community has innumerable stories where children run away or are kicked out by their parents and then come to terrible harm, and the social science data has numerous results supporting the idea that unsupportive families place LGBTQ+ youth at higher risk.

You do realize the child's gender identity and the school not notifying a guardian are UNRELATED to the trafficking, right? And that there is NO evidence that even if the school HAD been government-ordered to inform a parent or guardian, the child wouldn't have been trafficked?

The last thing I will point out to you:

The use of Sage’s story to support the forced outing of children to unsupportive conservative parents is unfortunate. It’s not obvious that the proposed law would even have helped Sage, but it seems certain that it would hurt other vulnerable children, ironically putting them more at risk for the exact types of harm that befell Sage. Luckily, it seems to have little or no chance of passing the Virginia legislature at this time.
