Earlier quoted context omitted.
Gender is an opinion, but it is a sufficiently coherent opinion across different people and different times that it can be studied and discussed from an almost objective historical and anthropological perspective; the "evil spirit" cannot claim that, for example, typical blacksmiths in stories are not male.
The word "typical" sort of turns it into a tautology. Whatever your idea of gender is decides which blacksmith is typical and which isn't.
The gender that blacksmiths in stories are described to be is typical or unusual with reference to stories, not to my ideas or yours. Do you recall any fairytale with a female blacksmith?
