Of course killing them is not the solution and would never be an admitted
behaviour in an evoluted world.
But a solution sometimes is necessary since such religious people
generally get politically organized and simply say (and may even "win" at
the end) that your robot
or human cloning, or anything else are "things of the devil"...and "against
god's wish" ...
Cause of such behaviour they are not so pretty good boys/girls...and we
always must have a more intelligent
(and stronger) response for them.
