Heroification
When we place someone on a pedestal and forgo the reality of their humanity thus erasing their flaws and our ability to perceive them humbly.
Helen Keller's story is a great example of heroification. We focus on the miracle of her ability to learn to speak and forgo the reality that she was a radical socialist. This retelling doesn't allow us to see her flaws and all, just like us. She becomes a hero instead of an ideal person.
