It's one thing for a biographical analysis to look at the person's real life experiences and relationships.
It's another thing entirely when you start conflating the characters in the fiction with the author's own character...
It is called reading with context. Famous examples being, writing "Age Ain't Nothing but a Number" song and then their career ends with long term sentence over underage abuse. Or making movies that center old men in relationships with young women again and again and then ending up in host of scandals over similar.
There isn't one because you can dislike a person and/or their works for literally any reason you want.
Is there a label for insisting that people put aside their feelings and engage with something because you have deemed their reason for not doing so invalid?
I only implied that implied psychological traits of a fictional character are not evidence of the same psychological traits in the author. It's merely evidence that the author is capable of observing or imagining such traits in others.
