Hogwash. I am a woman and I like physics. In fact, I majored in physics as an undergrad.
In your four (?) years as an undergrad, you got to observe 7 graduating classes: Yours, the three ahead of you, and the 3 behind you. Questions:
1) What was the average size of a graduating class in your department?
2) How many women students were there?
In my case, the average graduating class size was nine, and during my time there were a total of 3 women: two in my class and 1 two years behind me. Women in the "hard" studies seemed to prefer engineering disciplines to science disciplines.
My post was a joke to pick on women.
Don’t get so emotional about it. :)
