Okay so my definition might be: A woman is a genetic female characterised by a womb, breasts and a vagina. A very small number of women are born into the wrong body as men and then transition. Do you think this would cover it?
But your brain is your body.
If you are born into the wrong body, you therefore must have been born into the wrong brain too because every cell of that organ is coded with your biological sex.
As your brain controls all your sensations, your movements, your behaviour, and produces your thoughts, any sensations of dysphoria are a product of that biological sex-coded brain. If you are biologically male, they are male brain thoughts. If you are biologically female, they are female brain thoughts.
A transwoman's dysphora is the product of a biologically male brain. A transman's dysphora is the product of a biologically female brain. There is nothing outside of this physiological system that is sexed differently.
The only way to make the concept of being born into the wrong body make sense is if you either start advocating for the existence of the soul, which is a religious belief, or you talk about personality -- and we don't make laws on the basis of people's personalities.
Transgenderism is fundamentally a phenomenon where someone wishes to present, behave and be treated as an individual of the opposite sex because they believe themselves to be so -- but that belief is religious. You have to believe that there is something about the self that is "other" to the physical body and its mechanisms, and the "other" is somehow sexed in an opposite way. However, if this "other" has no material, physical existence, it cannot be sexed at all for it has no cells by which to sex it.
Asking people to accept these beliefs and their impact upon public and civic space is comparable to demanding that everyone convert to your religion.
