You are still not getting it. Dependent was predefined. You are saying the GOP defined the term, when they did not.
You don't even understand what the term dependent is, which explains this asinine quip "Did the fetus depend on the mother?"...that is not the definition of dependent.
You can play all the word games you want, but the words have meanings, and you don't get to change the meanings to fit your argument.
The unborn child is still alive, but you cannot claim them as a dependent until after they are born.
