There was a woman who used to write guest editorials for the local rag who was an arch-radical feminist. Everything she wrote was about some heinous thing done to some woman or women by some evil man or men.

I worked with a person at my last place of employment who knew her from high school. He said her attitude in high school was exactly like what her photo might indicate. A very unhappy, argumentative person who was dedicated to being miserable.
