On the contrary, they are very closely related.
You are on a conservative web site. When was the last time you saw a real pro-vs-anti abortion debate here? You are sniping at your own team, and it's weird and unhelpful.
Only for those that are pro-choice does it appear as sniping. For my pro-life comrades in arms, it is an acknowledgement of our our society's contradictory social mores---that a story like this gets press and the God-knows-how-many abortions performed today do not.
Besides, I disagree that it is unhelpful. It should be disturbing to a pro-choicer that I draw a parallel between animal cruelty and abortion. I'm glad it gets under their skin. That's what a conflicted conscience does to you. It's the ones that would casually dismiss me as a nut without response that are beyond my reach.
