Here are some excerpts from the blog you posted.
People in my clinic rarely describe gender dysphoria in clinical language. They describe it in physical terms. A cold wave that washes over them when they catch their reflection. A sense of looking in the mirror and seeing the wrong face. The feeling of performing in a play that never ends, where the role does not match who they are. One person described it to me as a kind of chronic pain that gnaws at them without any clear physical cause.
This doesn't say anything about what the condition is.
That embodied quality is one of the things that distinguishes it. Gender dysphoria is not just a thought about gender. It is a felt sense of incongruence between the gender someone experiences themselves to be and the body or social role they are living in.
OK, so here perhaps we're getting somewhere. It's about their body (so a type of dysmorphia) and the social role. Oh dear, we're back to the stereotypes.
The DSM-5-TR defines gender dysphoria as a marked incongruence between someone’s experienced or expressed gender and the gender they were assigned at birth, lasting at least six months, and causing significant distress or impairment in daily life
What, exactly is an "experienced or expressed gender"? Is this about social roles again - the stereotypical expectations around being male or female? Or something else? What exactly?
There is a persistent mismatch between someone’s sense of their own gender and the body or social position they find themselves in, and that mismatch is causing them real distress.
It's just nonsense - what is a sense of their own gender other than knowing what sex they are? Or is it just about stereotypes and wanting to act the part of the opposite sex.
Destroying the health of children for what? So that they can spend their lives cosplaying as the opposite sex?
I don't accept the concept being described because there is no concept being described, just meaningless waffle.
