Guilt by association
Rejecting an idea because someone disliked also holds it.
How to spot it
Is the argument that “a bad person agrees with this”, and nothing more?
Example
“You like that band, and so did a villain, so you must share his views.”
How to answer it
A bad person can be right about some things. Ask whether the claim is true.
