I'm really not, unless you're going to call the entire field of linguistics insanity.

When we call a boat or a building or a country by female pronouns, we are gendering the object/concept. This doesn't magically mean the boat now has a uterus and a womb. Gender, not sex.

Gendering concepts unattached to sex may be only on a specialized use case in English (only specific types of objects and concepts, and overwhelmingly female at that), but it's a natural human phenomenon (personification), and is a core backbone for many other languages, especially the Romances.

Books and comets and Mondays are male in gender, but that doesn't mean they have penises and testes. Tables and chairs and radios are female in gender, but that doesn't mean they can get pregnant and give birth.

Gender and sex are inextricably linked terms, but they are not synonyms. Both words have specific use cases the other does not apply to.

I hope this helps.
