Because inequality makes people's lives worse, makes them live in poverty, and forces them to spend their lives in conditions of oppression and hierarchy. This is a stupid question.
Poisoning The Well
It's not a stupid question where is your proof that inequality makes people's lives worse? A millionaire may be jealous of a billionaire but, even though they are not equal, the millionaire still probably has hir needs met most adequately.
Meaning and value is subjective, so we cannot justify the killings of people simply because the killer thought the victim's life had no meaning or value.
Life and body must be inherent properties only the owner can make decisions about for society to exist.
meaning and value are subjective, belonging to the individual in question and those associated with them. In this case the organism does not have the capacity to assign meaning or value to its own life and it does not belong to the outside world so no value can be ascribed except by the parents
Who is in the position to decide over this value? It is true that the parents are the owners of the child, but the child does possess his life, which only he can decide upon. And since a fetus cannot speak out its wishes yet, no action should be taken regarding damaging the child's life.
Fallacy Of Is To Ought
a fetus requires the care and significant resources of its mother. Just because a fetus is created does not mean that it ought to be supported.
