"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." - Manuel II Palelologus
I have learned to assess the women I work with with for feminist tendencies. At my last job, there was an older woman from Texas who fit the profile of a man-hater.
She had been married once, and was supremely bitter. Any gender related conversation was a potential minefield and she monitored office conversation, interrupting when she was offended.
I was very, very careful when in her presence.
