Yes, there are female Star Wars fans, but not as many as there are male Star Wars fans.
You should have said that from the beginning.
Regardless, you might ask yourself why.
Why are there more female fans of Sex in the City than there are male fans? Why were there more male fans of American football than there are female fans? Men and women sometimes have different tastes.
Because of our culture. Our culture says that men should like certain things and that women should like other things. There is a small biological factor, but it’s mostly culture reinforced since the time we are babies.
