No sexual orientation or gender identity is a mental disorder. Treating it as such by trying to change it or discourage people from expressing same-sex identity/desire or living authentically according to their gender identity - by licensed practitioners - is unethical. It is also potentially harmful, particularly for minors.
I can hardly believe that in 2019, Virginia's professional regulatory boards are just now considering putting something like this into place. Please follow through with this necessary process and follow it up by urging the Virginia General Assembly and the United States Congress to pass legislation making this illegal (and preventing adults to pay for it through Medicaid or Medicare).
