Agreed. Most pro-choice people I know similarly get very hesitant and/or oppose that procedure. It is for late term foetus abortions, and a sizeable percentage of people who are pro-choice severely limit their approvals or totally oppose such abortions. This particualr procedure also plays a hypertechnical game with 'birth' with the argument being that a person is not technically 'born' unless the person is fully out of the birth canal. This is viewed as a cruel and frivolous distinction for something that just has all the obvious signs of infanticide.
