See! Now you are getting it!
Just as "civilized" as killing other humans (post-womb) because they believed the world was round instead of flat (thanks Renaissance!).
Or killing them because have different skin colour or believe in a different deity (thanks Inquisition!)
Or traveling to another part of the world and killing people over there because they have stuff we need to fuel our greed.
Killing is killing, son!
Better get used to it cuz it's what humans (and your esp. your gov't) are so good at doing.
p.s. -- life is much easier once you stop pretending that humans are civilized! lol!
