It was wrong and he was old enough to know it. Even more horrible because it was his sisters, that really increases the ick factor.
I think that their approach to male/female relationships may have contributed to this. There is a ditch on both sides of the road and in their zeal to protect their kids’ purity, they didn’t help them navigate feelings well.
When I was that age I had been grabbed and groped by boys in my class and, sadly, it was considered normal. They had a “best buns contest” and we were grabbed in the hallways at school. Other reasons for other body parts. It wasn’t right but it happened and we all learned how to protect ourselves and the boys outgrew it, sort of. No one is calling them molesters now.
Neither situation was right and my teen boys were disgusted with the Josh Duggar story, and went into “told you so” mode as they mocked and ridiculed that show every time my daughters watched it.
It’s normal for boys to be interested in girls and when you make thinking about girls “dirty” then their minds can get messed up. I think that maybe happened in their family. I also think Josh may have a narcissistic personality, bordering on a disorder. It comes out in the way he talks and especially how he talked about this. He really needs counseling for the sake of his wife and kids.
He fessed up, took responsibility for his actions, and now he seems to be doing quite well. Success story! Oprah on the other hand remains a perverted sexual deviant.
Funny...the family has moved on quite well...
The Duggars were (are?) deeply involved in the of the Bill Gothard movement, which turned me off to them. Gothard ran his “Institutes” for years, setting himself up as some kind of authority, but accountable to no one. A lot of young women say they were abused by their leadership. The movement, has a lot of sexual weirdness in it:

The first time I came across this secretive wierd guy (more than 40 years ago), I had the willies.
