You kept bringing attention to the fact that ‘a 17 year old is a child’, as if the legal distinction was relevant to a discussion on morality. I addressed it because it was beyond the point. What happened to her was morally equally bad whether she was 17 or 18 at the time.
Earlier I mentioned that the legal age was 16 in the Virgin Islands. I was emphasizing that the legality of age was not the primary issue; the issue was the morality of taking advantage of a vulnerable person. I think we may be on the same side of this.
