Rivard was contextualizing the phrase, which he had told the Chetek Alert newspaper in December after a high school student was charged with sexual assault for having sex with an underage girl.
The comment was part of a story that Rivard’s father told him. From the Journal Sentinel:
“He also told me one thing, ‘If you do [have premarital sex], just remember, consensual sex can turn into rape in an awful hurry,’ because all of a sudden a young lady gets pregnant and the parents are madder than a wet hen and she’s not going to say, ‘Oh, yeah, I was part of the program.’ All that she has to say or the parents have to say is it was rape because she’s underage. And he just said, ‘Remember, Roger, if you go down that road, some girls,’ he said, ‘they rape so easy.'”
With those remarks, Rivard was trying to explain himself.
