Semantic Madness: Equal Hes & Shes

Shaykh Hamza Yusuf mentions in his talk on Women and Islam that he was attending a Philosophy class and the instructor said that to use pronouns as "he/she" combined so that both male and female pronouns occur at the same time. He asked, why do they need to do that? And, the instructor said not to invoke gender biased. Shaykh said, "What about genetic coding?" On being asked about it, he replied, "Male chromosome has both X & Y, representing male and female, but female has only her's. So is nature being biased here?" This is true for word he because it includes both sexes. He also mentioned that British have resisted this 'semantic madness', they don't wanna change their language - which as other languages is not biased.
