I am a feminist.
But hold the phone here. There are different definitions of different types of feminism. It is important to define what one means by feminism, and how it defines your outlook on life. If you take a university course in gender studies or women's studies, the prof will probably spend a large part of the term going into the different kinds of feminism, and the distinctions between the concepts of "sex" and "gender."
The kind I support is often called traditional liberal feminism. Basically it accords women the same social, economic, and political rights as men.
It is really, really important to recognize that so many assumed differences between men and women are the results of cultural norms, not intrinsic biology. Today, when I see professional women on TV wearing ever more skimpy dresses, with Barbie-Doll dyed-blonde long hair, and 5-inch stiletto heels, I just cringe. These are all matters of fad and fashion, having nothing to do with intrinsic conditions of being biological male or female.
I cringe at learning about the severe sexual harassment faced by women in the military. These women want to serve their country as professionals. They do not deserve the **** piled on them by insecure men who have trouble defining their masculinity in the face of female soldiers.
I look forward to a society based on the principle of "Free to be you and me," without stultifying cultural norms about what it supposedly means to be male or female. At some basic level, people are people.
What feminism is not at all about is hating men, women wanting to dominate men, or any of the other **** that anti-feminists paste on a social movement that frightens them.
