I didn't read the rest of the article but I wonder if the writer mentions what I jokingly said to a pro-choicer I debated on this matter, that abortion is wrong to perform on animals because it's not the animal's choice. (The response was more or less agreement, to which I responded "Funny how no animal chooses to get an abortion of its own free will in any case." Yes, I know animals don't have free will but I was arguing with one of those crunchy granola New Agey prochoicers whose apartment had a lot of candles lit.)
