You are arguing semantics. The specific words that the scientific community uses to refer to reality in their models of reality often change.

For example, “discomfort” in gender dysphoria is a scientific term that implies a level of suffering on par with the “discomfort” one would feel immediately after a major surgery, during the recovery phase, except this discomfort is chronic.

Scientifically, people experiencing gender dysphoria are considered to be in a state of chronic suffering for which there is a medical treatment, called gender affirming care.

Not all gender affirming care results in gender reassignment.
