I think he's still wrong. According to Wikipedia, sexual assault is an act in which a person intentionally sexually touches another person without that person's consent, or coerces or physically forces a person to engage in a sexual act against their will. Minors arguably cannot give consent. A lack of consent is all that is needed to meet this definition. It doesn't matter that Epstein enslaved her first.
