No. That's just utter bullshit. IF something is living parasitically off you, then you really do have a right to kill it. False dichotomies like this are just logical fallacies.
Additionally, given that the largest vocal group of opposition generally comes from christians, this opposition can't realistically be seen as anything other than congnitive dissonance. Their stupid fucking fairytale tells them that infanticide and human sacrifice is not only to be applauded but to be the core of their belief system.
IF you're so fucking serious about right to life, go and protest a palliative care centre, or a funeral home. Take your pathetic mental illness and stop waving it around like everyone else wants to see it. IF you don't think that your imaginary friend wouldn't like something, then don't do it. Stop fucking trying to impose your sick and twisted moral code - derived from a cult of human sacrifice - onto the behaviours and circumstances of other people.
