I thought of another one. I have read examples like "Outlawing
vaping is like telling people on the Titanic to stay off the lifeboats because they have not been long-term tested" and "Outlawing snus is like outlawing seat belts because people have been injured while wearing seatbelts, and providing seat belts might encourage reckless driving."
But as nice as those images are, they are too extreme for a lot of folks (though I still would like to make cartoons out of them.)
How about "Would you let your child who drinks milk and water and fruit
juice start drinking Coke or Pepsi all day? No, you wouldn't. But would you tell your uncle who drinks whiskey all day that Pepsi is not a safe alternative to whiskey if he was thinking of switching?"
