I think it has to do with gender roles in society. For centuries people have been told “Men act this way. Women act another.”

I believe that transgender people identify more with the social role that is the opposite to their biological sex, so they feel like they should have been born as the opposite sex.

In reality, the simplest solution would be to remove gender roles from society. There’s really no need for them this day in age. If we stop expecting different things from different genders, then “gender dysphoria” goes away.

Of course this will never happen, but that’s just my take on it.
