If you’re astounded at someone else’s “twisted” logic perhaps approach them with this:
The purpose of government in the United States is to allow as much as possible to each person Life, Liberty and the Pursuit of Happiness.
The laws of the nation are how the government creates conditions for moral conduct.
Also in the United States, the people collectively are the source of the government’s authority.
The laws of the US must conform to the moral decisions of the people.
Many people in the US are religious and their faith informs their moral decision making.
Individuals’ moral decision making can (must!) include consideration of the individual’s religious moral teachings.
To allow or restrict Abortion is a moral decision.
US laws can and should reflect restrictions on abortion where the people – informed by their moral decision making including religious teachings – decide it is appropriate.
