human - but you ARE a feminist if you believe in equality of the sexes! There were people who didn't, in fact, through most of history that was the dominant view! And there are people who continue to believe that now.
Of course, there are many, many varieties of feminism - there are serious, deep, and passionately-argued differences between them. I am a feminist, I vehemently disagree with certain other types of feminism, including the one that prevails on Mumsnet's feminism boards. I deeply dislike the work of certain women writers in the tradition to the point that it enrages me to read it, and I've devoted considerable time and energy to debunking their arguments. I will, however, fight for the right of all women to have their differences and to argue them out!
What you are talking about, however, is popular perceptions of feminism. That's like the difference between astrophysics and people's perceptions of Mars. There are probably people whose first association with Mars is "little green men"! That does not mean that there ever has been any evidence of little green men up there, or that astrophysicists are sending probes up there to look for them. It's an old-fashioned, erroneous association that somehow persists. Of course, it's a problem for feminism - but it's been caused far more by male fear of womens' equality (and smears on feminists as smelly, ugly, lazy lesbians) than it ever was by the movement itself.
