Depends what definition of “normal” is being used.
- As a stats person, I would use the term “normal” to describe a condition which is in an arithmetic majority.
- However, if I put my old biology major hat on, “normal” is defined as “naturally occurring” (as part of the normal diversity of species).
You can see how a transperson does not meet the former definition, but does meet the latter.
Not judgin’, just sayin’. It’s important to understand what definition people are using when they speak, and not assume.
