Women who acquired men's freedom
They are known as burrnesha, or sworn virgins.
Young Albanian girls are/were forced marriages to older men. Freedom to vote, drive, earn money or own property were only for men. A family suddenly without a male would lose everything. For that reason some became Burrnesha, sworn virgins, biological females who chose to take on the identity of a man for life. Some likely non-binary anyway and may have been most comfortable with that.
The position they take may be interpreted as gender being social construct in the true sense.
