I think abortion is really a relative term. I know girls at my high school who use abortion has birth control. They have sex, unexpectedly get pregnant, and then get an abortion. They do this over and over and over again. For these girls, yes it absolutely is the easiest way out.
I think what Julie was trying to say is that it's the easiest way out physically, not mentally. For teenage girls, their appearance is everything - some would rather suffer a menta breakdown from an abortion than get "fat" because of a baby.
