Part of the problem with the way the book is perceived is with using the word ‘Lolita’ to describe the girl in the book. The girl is named Dolores and is a rape victim. Lolita is a primped up name that Humbert makes up for her. No one ever calls her that in the book - nor does she use that name. When calling her that you are inherently adopting Humbert’s perception of her as a sexualized object.
Lola is a variant of Dolores (Spanish for "sorrows," a reference IIRC to Mary as Our Lady of Sorrows), and Lolita is of course the diminutive of Lola, so there is a connection, even if the name is only in Humbert2's head.
