Argument against prenatal testing from the disabled community: Suggests the lives of the disabled are not worth living Should we test? For what?
Countering such arguments: 1. Prenatal screening expresses a hurtful message to those who live with disabilities. The reasons that people do prenatal testing and screening vary. No message is being sent. There are lots of things that people do for their own reasons that some may disagree with or find problematic, but these decisions and actions are not about them or sending messages to them. 2. If screening leads to a decision not to bring the disabled child into existence, then the message is that a person who has a disability is unworthy of being born. Person Subject-of-a-life Birth Viability Fetus Embryo Zygote-implantation Egg But this confuses an already existing person with something that doesn’t exist.
