Fair article with couple of notable omissions:

Funding issue: 
Consider socially progressive Netherlands: Funds all schools, public and charter. Moreover, religious / philosophy based schools are constitutionally protected, allowing them to deny applicants who object to the schools philosophy (which rarely happens). 

Science issue:
The 'science' is still very immature and incomplete on the subjects of gender dysphoria, homosexuality etc.  As such,  it is far too premature to respond to gender confused people by prescribing dangerous hormone treatments and/or irreversible physical mutilations.  The fact that 'exposure to higher levels of testosterone in the womb is associated with masculine behaviour' should be a wake up call for scientists to finally start exploring the effects of endocrine disrupting compounds (EDC) on human development. Once we have a cause, we can develop a cure. In the meantime we need to treat these conditions with compassion and non-invasive treatments.
