Put to one side your Kate Millets, Germaine Greers, Nina Powers, yea even your Kat Banyards. The book everyone needs to read IMMEDIATELY is Delusions of Gender by Cordelia Fine.
you will laugh, you will cry, you will rage, but mostly laugh, especially at the bit with the dead salmon.
basically you have to read it as it means nobody can ever pull any 'oh but men and women are different, they have different brains' stuff on you ever again.
