You had to "pull a Repub", didn't you? "Pull a Repub". It's a new term I've coined to denote when one twists or deliberately distorts the conversation. Anti-abortionists are masters at it.
We were talking about DNA and DNA can only tell if something is human material. Material. DNA can not tell, specifically, where the material came from, thus, it can not tell if it came from a liver cell or a fertilized egg or a toe or anywhere else. That is why it's nonsensical for one to say DNA can prove something is a human being. It can only determine if something is human material.
So, as to your statement implying I said "science" can't discern the difference between a liver cell and a fertilized egg you deliberately twisted what I actually said which was DNA can not tell the difference. You pulled a Repub.
