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.
The latter is another one that you’re not quite as right as you think you are on. Rabid football fans are split almost evenly between men and women these days.
But is it a problem if more men than women like Star Wars?
Why should it be?
There’s no reason why Star Wars should appeal more to men than women, and yet it does, due to cultural/societal bullshit. I think it is a problem, though to what degree is definitely up for debate.
