When did I ever say that? Also, a fetus is not just a 'bunch of cells'. A fetus is the stage in prenatal development when organ systems, bones, and organized human tissue form. Fetuses are far more complicated than a 'bunch of cells'. I think you're looking for the word 'zygote' or possibly 'blastocyst'.
I think you have misinterpreted me and then I misinterpreted you. I said something about how food does not carry DNA. (As opposed to a fetus). To which you responded by comparing DNA to an actual human. I interpreted you talking about comparing DNA to an actual human as though you were comparing the fetus which contained the DNA to a human, which was the subject I originally mentioned.
Also, I am not referring to a totem pole of civil rights, but rather the totem pole of considerations when ending life in general. For example: Nobody cares when you pull the head off of a flower, but people usually care if you kill their pet dog. If you accidentally cut yourself, a few of your blood cells might spill out and die in vain. I think that the life of a human fetus/the cells that make up the fetus should be more carefully considered than the life of other cells or fetuses.
But I do agree with you, that excessive worrying about non-conscious beings is silly.
