Critique of 'keep abortion safe, legal, and rare' — internal contradiction if the unborn is not a person

Mike argues that if abortion does not kill a real person, there is no reason it needs to be 'rare.' He uses the analogy of dental work — we want it safe and legal but not necessarily rare — to show that the 'rare' qualifier implies even pro-choice advocates tacitly acknowledge something morally significant is happening. He attributes the phrase to Hillary Clinton.
