I basically agree with LukeASomers. I would suggest not changing examples. They are both of the form "X is Y." Just use one so it is easier to see what distinguishes "implication" from "inference."

Also, it needs to be more clearly stated that the implication fallacy is on the side of the person making the statement while the inference fallacy is on the person interpreting the statement.

(Note that this goes the other way, too. If they were implying simply that they enjoyed the book or were affiliating themselves with a tribe and you inferred they were making some factual claim, that would be just as wrong).

This actually seems like a good example of both parties committing their respective errors. Consider stating that directly.
