Question: Official term for "whataboutism"?
It seems to me that this is clearly a non sequitur. The full syllogism, as I see it:
P1: A person who jaywalks sets a bad example.
P2: John jaywalks.
C: John is setting a bad example.
Saying Delores jaywalks does nothing to refute either of the predicates. It also doesn't counter how they logically reach the conclusion.
Delores's behavior is totally unrelated to John's behavior or the example it sets.
