We can agree to disagree on many things: Chevy vs. Ford, the designated hitter, pulp or no pulp in your morning glass of OJ. You might like mustard on your hot dog. It could be a preference for Miller over Bud or black ink compared to blue ink pens. You might secretly dig kitten boxing, or Japanese cartoon porn. Some people actually root for the New York Yankees and New England Patriots. There is no accounting for individual taste.
But on one subject there can be no mistake. If you choose something besides smooth Jif peanut butter on white bread, you are just plain wrong.
