If you are ever in doubt about whether to ask some burning question, first ask yourself if you would pose the same question about the body of a non-trans youth or adult, perhaps your own child or a student or neighbor. If the answer is no, don't ask. If you find yourself biting your tongue, keep biting.
For parents of kids who are transgender, gender education alone isn't going to provide that reassurance. What I think would really help are more everyday success stories -- people who can show trans kids, their parents and society as a whole that being transgender doesn't have to forever define you (unless you want it to).
This needs to end now. Those of us with the resources to fight in any way need to continue to stand up to those who are actively working to see more trans people dead, and we need to be absolutely present with those trans people who, at any given moment, may have fewer emotional or material resources than we do.
Doing something that is totally inconsistent with previous behavior and runs counter to personal philosophical and spiritual beliefs can nonetheless free one to live in a more positive and healthful manner. It's not a cure-all, but it gave me the tools to overcome stigma, live authentically in service to others, and not see myself as a victim.
