OP. How do you believe someone is born in the wrong body?
Which other group of people have been 'born in the wrong body'? This has become another euphemism used that hides the reality.
No person can ever be born in the 'wrong body'. They may feel that they are not happy with how their body looks or works, but it is not the 'wrong body' for them. It is merely their body.
Genuinely, have you tried to analyse this?
I posted this before, but maybe it will help you think about this concept that you have that a person can be in the 'wrong body'. They associate being a 'girl or woman' with their feelings that they are not a 'boy or man'. That is all it is.
It comes down to their own philosophical belief that what they are feeling is that they are not the 'sex' they materially are. This can be for many reasons.
But can you tell us why this belief should be affirmed and any other identity belief that is not based on material reality is not affirmed by society?

No male can ever experience life as a woman. They can only ever experience life as a male person who believes they are a woman.
Even when they 'act' like a woman, they are acing as they believe a 'woman' should act.
Even if they are treated 'as a woman' by some people, they are being treated as a 'male who presents as a woman and believes they are a woman'. Because their every reaction is based on that. Not on them being female in any way.
Even when they have extreme body modifications, it is to be their own concept of what a female looks like to them. It is not what a female is. How can it be?
The only way a person can experience life as a woman, is to have a female body, formed around the production of large gametes, even if it doesn't produce those and to navigate their life based on the decisions they and society makes that revolve around them having that body.
A male can conceptualise what it might be like to be a female, but that is all it ever is - their concept of being female.
They may do it because they don't feel they fit into how they conceptualise how a male person interacts with the world (ie. their own stereotypes around being male) or they do it because they want to be seen as a female (using their own stereotypes of how a female navigates life). It really doesn't matter though. Their motivation is irrelevant to the outcome. And I consider the outcome can only be described as misogyny.
Which is that they will always be just a male who believes they are something they are objectively not.
How can the material reality be any different? This is why someone's gender is only based on someone's philosophical belief. And philosophical beliefs are fine for people to hold, but not one person in the UK has to comply with another's philosophical belief.
The logic cannot be any different than that I am afraid.
