I think you're getting it backwards. Perhaps willfully.

All people use cultural cues to signal their place in society. (I have a degree in culture studies, incidentally.)

Young trans kids - preschool and young elementary schoolers - particularly rely on these cues.

Why? Because they lack the models and language to understand their unusual position in the world.

So if they have penis and feel they are a girl, they do girl-coded stuff (like wear pink), to communicate that.

is pink fundamentally female? No. That's a cultural value. And a problematic one. But it doesn't make it not real.
