It really isn't. From the very first episode/chapter/release...it was split pretty evenly and has been ever since. The original story may have been, but for the AVN conversion, a purely femdom game would never have lasted (or made enough money) and she knew this.
One of the reasons it was released here first (and her being very active here)...despite her now hatred of the place, the place that got her known, made it successful and are majority dom players.
