The idea of 12-14 year old girl actresses playing prostitutes/sexual objects is more than a little disturbing to me.
You conflated the creators of fiction about a pathology to actual perpetrators of that pathology. That’s what’s disturbing. Not to mention the fact that both Taxi Driver and Lolita (the novel anyway) are revered American classics. Jodi Foster was doubled by her older sister in the more suggestive stuff in TD.
