that is true

It is true that there was a cultural shift in the 60/70's. There was a rebellion against tradition - the hippi culture, Vietnam war and a total release from traditional cultural norms. This cultural shift in ethics was a discussion by philosophers that time. Should all sexual moral norms discarded or what would be the base for "desired" sexual restrictions. Finkelhor worked at the "Family Violence Research Program", so he can be considered an anti. However, in this 1979 paper he acknowledge several important facts: children are sexual, most are most likely not harmed, harm cannot be the moral ground for restrictions, and consent might not be the right substitute. If Finkelhor would publish this today, he would face a backlash for stating those facts. However, that paper might be the most progressive paper from him. He became a hardliner after that. Most likely he would deny those facts as false today. That might be a reason that his paper is not freely available. And yes, his paper is an example for ...research in soft sciences is too often strongly biased towards the justification of the current social order,.... But the "consent" term comes from medical procedures and research - where one has to accept possible consequences while not being able to do anything about it.
