And the lyrics presented are not about raping thirteen year olds.
The song starts with statutory rape of a child. When Nugent is confronted by the police in his song for his statutory rape, he suggests forcible rape as a "solution". Depending on the state the song happened in, it could also be child molesting.
Beyond the song, Nugent adopted a child for sex, which is statutory rape, and because he went over state lines with her, also child molesting. Under modern laws, just the adoption alone (taking control of her) would have gotten him to child molesting. Having a baby with a 14 year old girl is statutory rape, and could be child molesting depending on the state laws of the time. Getting oral sex from a 12 year old is almost definitely child molesting.
Piece of random advice for anyone who wants to molest underage girls, do not bring them over state/international lines. That gets you into the more strict federal laws. This all brings us back to trump.
trump's semi-fake modeling agency transported hundreds of girls over international lines, only to have them sexually abused. trump's defense to this is that he might not have known they would be sexually abused. trump transported two children over state or international lines for Epstein to sexually abuse. Again, trump's defense is that he might not have known they would be sexually abused.
My counter is why on earth would he be transporting children to a single man in his 60's? There is some level of duty to keep children safe when you transport them. trump obviously did not care the least about this duty.
