I personally detest the modern scientific thought-frame that its just "a clump of cells". That terminology seems Orwellian to me, and is a slippery slope to quickly dehumanize the subject.
I'm in favor of a choice to abort in special circumstances such as rape or mental defects, but then again that simply opens the door to more loosely defined slopes. Its like...where do we draw the line? Its either 100% yes or 100% no.
unless I am talking about my uterus, its not my place to have an opinion.
its a sensitive topic, and its nobodies business besides the pregnant woman, and her health care professional.
I guess you could say I'm pro-choice.
