Your body does not have 2 heads and 2 different sets of DNA.
Clever image that sums up one part of the illogicality in the feminist claim that the moral issue of abortion is largely limited to the assertion that a woman does what she likes with her body.
The other part of the irrationality in that pseudo-argument is illustrated by what I wrote in my previous post Legalizing Infanticide or Limiting Abortion:
What is absurd is for women to shut all the discussion by saying "it's my body, so I decide".
It makes as much sense as for a killer to say "I used my hand to kill, the hand is part of my body, therefore no-one can tell me what I can or cannot do with it".
The fact remains that, even if a foetus is inside a woman's body, it is still a different living, and in some stages sentient, being, so should not be treated just like an appendix of her body.
