to kill part of a person
You are completely ignoring his question.
We say 'fetus isn't human because it is not a soul'.
You reply 'fetus IS human because it has human DNA'
We counter 'so a skin tissue must deserve the same protection'
You then say 'skin is not human, though'
IOW: Make up your mind! Does having human DNA alone make you human or not? Is not something else needed? I say yes. You say no and then yes and then no.
