Just two things about your stage shot - it's a large rocket, with several motors, and it's a close-up shot of the separation. Atlas or Titan. To grab for "apples and oranges" is a sure sign you know your fraud is mighty thin.
Actually, it’s a Saturn.
So, let’s say the fact that it’s a Saturn (or an Atlas or Titan ICBM, odd that you would object to relatively small rockets in the same rough role) makes it poor evidence. There still is nothing...NOTHING...in the picture you posted that indicates a stage separation.
So, to use your metaphor, at worst I have compared an orange to an anchor.
And just to review...no photos, video or eyewitness accounts of a stage separation. And we still have the matter of the guy photographing an SLBM with a $900 Nikon 5 minutes after launch.
