"Experts" do neither their science nor their society any favor by declaring fringe, minority behavior "normal" when what they mean is that it ought to be considered "acceptable". Those are two different things. But it lets the cat out of the bag to state openly that they wish abuse of children to be acceptable, because it simply isn't and it isn't going to be.
From South Park...
Lead Agent: [to NAMBLA leader] We’ve been after you for a long time, buddy! Do you know your rights?
NAMBLA Leader: Rights? Does anybody know their rights? You see, I’ve learned something today. Our forefathers came to this country because...they believed in an idea. An idea called “freedom.” They wanted to live in a place where a group couldn’t be prosecuted for their beliefs. Where a person can live the way he chooses to live. You see us as being perverted because we’re different from you. People are afraid of us, because they don’t understand. And sometimes it’s easier to persecute than to understand.
Kyle: Dude, you have sex with children!
NAMBLA Leader: We are human. Most of us didn’t even choose to be attracted to young boys. We were born that way. We can’t help the way we are, and if you all can’t understand that, well, then, I guess you’ll just have to put us away.
Kyle: [slowly, for emphasis] Dude. You have sex with children!
Stan: Yeah. You know, we believe in equality for everybody, and tolerance, and all that gay stuff, but dude, —— you.
