Another analogy that makes sense to me:
Many years ago I lived in Florida and I took my young family to a park for a cookout. Not far from where we were picnicking I spotted a 7-8 foot alligator laying in the reeds down an embankment. This alligator was a problem for me as I was concerned for the safety of my children if that alligator should decide to come up the embankment.
A little while later some folks near us also discovered the alligator. They started tossing food from their grill down to it because they thought it was fun to watch it eat. I saw this as adding to my alligator problem, but I did not see these other people as alligators. They were just ill-informed and didn't know they were making it more likely that alligator was going to become a real problem.
