Do you think this woman is ist for writing a book called 'How Not to Look Old'?

um... she is most likely. ironically so if you ask me. The greater question here though (because you are obviously obsessed about this) is are you ist. You feel that a women that you have no business calling anything, that thinks she is trying to empower women is ist, yet you are so looking for it. Its like people that lay in wait to call you racist or a bigot. Your prejudices come out more when you call someone else something, trust me.
