My first reaction is that it is offensive to refer to women as a body part.
But then I remember that liberal women have been campaigning for years to be thought of as nothing but walking genitals. These days, they've even taken it further with the "slut" movement--tirelessly advocating to be thought of as nothing more than mobile genitals who exist only to pleasure men. (Never mind that that was the exact stereotype of women that 1960's feminists mobilized to fight.)
So, carry on. It is appropriate to refer to liberal women as a body part, as long as you recognize that *conservative* women are thinking rational human beings.
Of course they are.
If they weren't, they'd be liberal. ;-)
