This is a great line to use if you want to suss out whether or not this female has any brains in her head to maintain linear, logical thought (obviously a rare breed). This is what you do:

Whenever a woman asks if I am feminist. I will do two things. First, I ask a leading question like "do you mean feminism as equality between the sexes?" She will always say yes. Then, I immediately flip the script and ask if they are a masculinist. Indeed, if someone were truly for equality between the sexes, the terms "masculinist" and "feminist" should be used interchangeably. If she says yes, there may be some hope. Likely, however, most women when put on the defensive in this manner will immediately revert to the warm blanket of emotional response. Feel free to shame her in return, or better yet, just make a mental note that her cognitive abilities not up to par (that is, don't waste any more of your breath).
