If I claimed that the Lord of the Rings trilogy does not contain a character named "Frodo," would you call that a deliberate lie or a simple mistake?
I'd call it neither.
You'd be wrong, but maybe you were confusing the name, or maybe the book, or maybe it's spelt differently in a different language. Maybe you read it long ago and forgot. Maybe you read a printing done by a little known cult that censored all referenced to hobbits. I have no idea why, but there are an infinite field of possibilities and only some require bad faith.
Sure. But I think it is inadvisable to claim to know the reasons or motive behind the comment, and doubly so to claim they are acting in bad faith.
I don't have to worship a person to think it's inappropriate to use lies to discredit that person. In fact, the more worthy a person is of being discredited, the more important (and elementary) it is to discredit that person using true statements.
