I'll tell you what, I've had to come a long way. I have a military background, and I came up with Bill Clinton and DADT. Not a great time to be gay in the military, and I bought way into it. About 2015 I think it was they got us all in a lecture hall. A couple legal officers came in to give us read-along PowerPoint on DADT going away, which sucked, so a sergeant major shooed them off the stage and basically told us, "They're here, they're queer, get used to it. Keep your god damn opinions to yourself, and I don't wanna hear about any of you fuckers having a problem with it."
So, I got used to it. About a year before my own kid came out, I could see it coming. I started quizzing my now openly gay colleagues, "So how did your parents screw up when you came out, and what can I do to avoid that?" I was so ready for it when it dropped. " You're gay, honey? We gotcha. Your our kid and we love you being you. "
Then the non-binary thing happened and I was more like "What in the hell is this?" I was advised to be supportive by people I trusted, so I bit my tongue and went along to get along. Before I got used to this one, the trans thing got going. Your name is what now? Well at least it's better than the non-binary name, but you want to get what done to you?"
Well, I learned all the rules about living with trans people, read what scant research there is on gender dysphoria and hormone replacement, and decided that my kid's life wasn't mine to run, our insurance was pretty good, and on balance I could live with it if we did it the right way.
Therapy, referral to specialist therapy with a certified diagnosis, pediatric endocrinologist, follow up therapy, the works. I am now even familiar with the process for the name change of a minor in my state. Every step is kind of a wrench, because as a parent your kid is always your little boy or girl, and that's not easy to let go of. We're doing the best we can, and I've realized that my not understanding something does not make it untrue.
So, yeah, I'm glad you all find this educational. It's been a got dang education for me, I'll tell you what.
