This person is containing their gender as a private string, which would be a line of plain text contained on their own machine which would be free to edit, and not as a public constant Boolean, which would show on everybody’s machine, would be read only without possibility of edit, and would be a binary true false statement.
So basically, “It’s my gender, it’s not a binary, and I’ll do what I want with it!” π€πππ€
also “you are not entitled to know it"βsome private variables have "getter” methods that allow others to read the value, but many also won’t, and will only be accessible to their owner!
