I've got a question for the doctors who confidently assert that the 24-week fetus is at the Sgt. Shultz stage of human development ("I feel nothing, NOTHING!").
If it were possible, would you be willing to go back to being a 24-week-old fetus and submit to an abortion procedure to test out your hypothesis?
Because, even if you're right and you don't feel a thing, the procedure will, you know, kill you and remove all potential for you to enjoy your life on this planet.
