One of the reasons I consider myself a feminist is because rights and respect are not a zero-sum game. I firmly believe that a society in which men and women (and other, and in-between) are treated with an equal amount of respect (note: not identically) is possible, and feminism is the most realistic plan for creating that society.
Giving women more power to control their own lives does not take away your power to control your own life. Giving women more respect does not require that you lose any respect for yourself. Removing unfair laws that restrict what women are allowed to do with their own bodies does not create laws that restrict what you’re allowed to do with yours.
In other words, the only people who really lose anything because of feminism are sexists, specifically those who rigidly enforce gender roles (which we as a society figured out were a pretty bad idea somewhere around 50 years ago). Insisting that women and men will just always be inequal is defeatist, and also illogical considering that we human beings are capable of amazing things, including creating a more inclusive society (2014, despite what pessimists say, is a hell of a lot better than 1014). So really, what’s the problem?
