  The expressivist argument is often defended by theorists who are staunchly pro-choice about abortion; they typically defend a woman’s legal right to choose abortion for any reason but present a moral argument against particular reasons for selective abortion. In making this distinction, they rely on the “any/particular” distinction proposed by Asch (2000): a woman who does not want any child because she is not ready to be a mother is different from one who is eager to be a mother but then rejects this particular fetus or embryo, based on screening. A different version of the expressivist argument looks beyond the individual act of testing to focus on the social offer of prenatal testing, particularly in a society where it has become routinized, to consider the negative evaluation it expresses about the lives of existing people with disabilities (Press 2000).
