Prejudice takes many forms. People discriminate on the basis of race, skin color, religion, ethnicity, social status, age and, yes, gender.
I grew up being angry about gender bias. It still makes my blood boil to hear fundamentalists from my religion, Christians, Jews, Muslims, and all the rest relegate women to a second-class status.
My reasons for feeling this way are very personal. I was raised by a single mother. She worked hard to make a living for her mother and three children. Can you imagine how livid I was to learn that my mother made less money than her male counterparts simply because she was female? I grew up thinking that right is right, wrong is wrong, and this was wrong!
Prejudice, regardless of what form it takes, is wrong, and we all need to become less and less tolerant of it.
