From my wife:

I learned many interesting and useful things from my Women's Studies class, and am glad I decided to try it out. However, I became a pariah when I questioned the professor's account of sexism in biology textbooks. "Eggs are portrayed as passive, while sperm compete to reach them." In my experience, textbooks say what actually happens in the reproductive system, with no sexism to be found. She stuck to her guns. It was unfortunate that she used that example, because there are real examples of gender bias in biology publications.

And back to me:

Just thought it would be useful to provide an example of a questionable claim. She says other people in the class hated her for pointing it out.
