I agree that their request is unreasonable, and I'm sorry for the stress it's causing you. I can't really justify their behavior on a rational basis (teens, right?). And obviously I don't know your child, and I don't know you, but as a trans person who went through a similar phase, maybe consider what they might be thinking if you want to understand why they might be behaving like this?
For one thing, they almost certainly know your opinions about the persistence of trans identity and online echo chambers of gender identity. If (real if) you're hostile to the idea that they could really be trans, it's possible they feel hostile to the idea that you could really be making a good faith best effort to support them, which is what this sounds like to me: defensiveness. I had a very similar dynamic with my parents for several years. We came out of it understanding each other a lot better, but it was certainly rough in the thick of it. I really hope you can find a way to resolve the tension.
True, you don't know me.
When my child came out as pan, a few days later we had arranged for a trip to an old friend of mine who is a trans-woman, a lesbian, and who had a non-binary friend who was staying with her.
I regret the fact that you had a difficult relationship with your parents. I've seen that story play out. However I'm pretty confident that I'm not actually transphobic. My concern is not that I don't want a child who is trans, my concern is about what is best for my child's long-term well-being.
It’s one thing to be supportive and empathetic. It’s another thing to bow down to worship your child and let them run the show.
The trans issue has risen to a point where society must face it and figure out the bigger questions of how can we accommodate them and yet balance and find natural limits. We are so fucking far away from that point. And we will get there eventually.
I agree with the parent comment saying the trans issue is way over sampled and is or has become some kinda trend. It just is. Clearly their child showcases the main point of children know nothing when the child mis-understands what true transphobia is versus a childlike ignorance of parroting a concept they just heard about. Why is that? Well it never changes from generation to generation. If you have kids at some point they learn about attention and how to use it.
It’s kinda like personal preferences. Is it transphobic to say you are only attracted to the opposite sex and would never date or consider a trans person in a romantic relationship? Nope. But it’s a sure fired way to keep eyeballs on the screen and people in their rigid political groups.
Like this parent (although I will be more brutal) I could give two shits if they felt they were a trex or were a girl or a boy. I don’t care. What matters is that I raise a kind hearted, compassionate human being who understands the world is not your friend. And can find their grit and true will when they need it. There’s book loads more to this but boiled down I’m doing my best to not raise an inconsiderate asshole. Because they must be held to account and told when they are in fact acting like an inconsiderate asshole.
Sorry to say it that harshly, but this is basically shutting down any discussion.
To what end?
Being a teenager is really confusing to begin with, and the last thing children need is more ways to categorize and divide people into clumps.
When your kid's demands are as simple as "hey support my identity, which requires nothing but thinking slightly more about the words you use" how could they not be frustrated when their parent can't even clear that low bar.
How do you define denying the first part?
According to my child's world view, I need to ask them every day what their pronouns are today. And any accidental slip-ups on any adult's part are a demonstration of transphobia, which justifies a raised voice and lecture.
While I'm perfectly OK with making an attempt to treat people as they wish to be treated, at what point does the inconvenience and stress that your constant demands make on others become an unreasonable ask of them? (Which is a question that every parent of teenagers winds up asking at some point, for some reason...)
