The REAL danger is the mirror of Humbert
In 1969 The Prime of Miss Jean Brodie [English movie] forecast what was to happen in 1970 with the small f feminist takeover of the so called nuclear family [ie the American Beauty that exists to this day].
The culprit was Germaine Greer and her book The Female Eunuch, and she was very much a "look alike" for Brodie, and in fact styled herself on Catherine from Jules and Jim 1962 [French movie].
If you have not seen Brodie I urge you to see it to compare Lolita as having matured emotionally by 17 having "got her wild oats" at 14 or so as opposed to Jean who missed her wild oats at 14 and became totally obsessed with that fact, and a DANGER to those she influenced as a school teacher.
The main difference Greer to Brodie is that young Sandy STOPPED Brodie but nobody stopped Greer.
In Lolita, the only harm Humbert could have done [apart from to himself] was perhaps to "emotionally harm" Lolita, but as we saw Lol was years ahead of Humbert emotionally, did the chasing and at the same time was having it off with Quilty and ending up in a very healthy, mature relationship with a husband by age 17.
