I love Emma Watson. I greatly admire her and I think she has a lot of potential... but I do not agree with her statements about what feminism is.
Dictionary definitions are not the end-all, be-all of what a thing is.
I say this as a woman... indeed, as she said, a woman who has chosen to not associate with feminism. But I did not come to this conclusion because I believe that all feminists hate men, or because I think they are too strident in what they say.
I am not because the community has become irrational and poisonous, too many who are hateful and too many others who deny the existence and feminism of those hateful people.
I am not because I am a humanist, and I approach all issues as a human issue first and a particular group issue second, and because I include men and boys and other non-women as also being victims of most of the issues feminism addresses, I am frequently (in fact, pretty much always) told that I must be a man because I am concerned for the rights of men, or that I am turning it into something to gain attention for myself, or that while I am right that there are also non-women who are involved it is not the right place or time to discuss it... and the "right time" never comes.
I am not because I understand what a No True Scotsman fallacy is and I will not accept it as an excuse for the nature of the feminist community.
I am not because I am tired of the harassment I receive from feminists for agreeing with the issue and simply expanding it to include all people, and for having other "moderate" feminists defend themselves first before or instead of acknowledging the problem I have presented.
I am not because the word itself is gender biased, implying that only by acting for women's rights can equality be achieved, when in fact presenting any issue as being a "women's" issue is in and of itself divisive and discriminatory.
I am not because gender egalitarianism and feminism are not equivalent and cannot be used interchangeably.
I am not because I will not willingly associate myself with hateful, ignorant people like those I described by using a word that does not properly identify my views to begin with.
Yes, I am ENTIRELY in favor of eliminating sexism from society. However, I will not accept that including all people and having a broad-scope approach to what sexism is and how to treat it in any way detracts from its progress. If we are to have any sort of comprehensive approach to eliminating this problem, we MUST do away with this concept that any problem is caused strictly by men or suffered strictly by women. It is absolutely not true.
Remove those blinders. Call a spade a spade.
