Incorrect. Historically they was the gender neutral singular. Defaulting to male was a much more recent change to language (very late nineteenth century).

Tho language is not immutable.
Depressed how many people want me to just accept it. "Come have a happy fantasy experience, but in exchange accept constant misgendering without complaint."
