This is a false equivalence- Hillary would have to say that she wanted to "walk up to ghaddafi and open-hand grab his testicles" for this to be a proper analogy.
The objectionable thing is that it indicates that Trump has, on multiple occasions, grabbed women's genitalia without their consent, purely because he's a celebrity and nobody stops him.
If Hillary had said that she had gotten Col. Ghaddafi "by the balls", I agree that nobody would have batted an eyelid because everybody would have understood that she was not discussing a situation in which she habitually sexually assaulted men and was able to get away with it because she was the Secretary of State.
