The recent ruling in Alabama that fertilized eggs used in the in vitro fertilization process are persons has revealed a critical flaw in the pro-life argument that life (personhood) absolutely begins at conception.
Now they are going to have to explain why personhood doesn’t begin at conception, rather it begins at inception. IVF perfectly demonstrates gradualism because the fertilized eggs that are necessarily destroyed in the process is ok because it is less valuable than the ultimate child that results.
And the mental gymnastics that the politicians are going through to make an exception for IVF only confirms gradualism.
