had some kind of "disease" (viral, bacterial, etc.) which threatened the entire species/planet, what would you do then?  Let the entire species go down with the ship out of political correctness?  Where is the Communist Party in America today?  Why isn't one of its representatives never seen on current American ballets?  If aliens came from space and were threatening the entire human species, what would you do?  Mill around like cattle, waiting for the hammer to fall?

Need any more analogies?

In the end, might makes right. Nothing has changed since the caveman.
