If you've been watching the shows, then I'm sure you saw the show where Michelle and Josh discussed that kissing wouldn't be allowed until the wedding day. Josh asked Michelle if it would be okay to hold hands when he and Anna were engaged and she said that would be okay, but that is all that happened until the wedding day. They made a big deal about waiting until the wedding day for the first kiss.
On another episode, the producer was asking one of the girls about not dating. She said that their parents allowed them to choose courtship. The producer said something like, "Well, what if you decide you want to date?" The Duggar girl said, "That's not an option." So while I think courtship is promoted as being a "choice," it is really the only option allowed. Not much of a choice if you ask me.
Just curious. When did you ever see the Duggar girls wearing pants? I've seen the little ones wearing bike shorts under their skirts, but never the older girls.
Josh was taking college classes online at one of the colleges that Bill Gotherd runs. There is also an online midwife program associated with Gotherd. While the Duggars say that the kids can go to college, it's never been made clear that they will be allowed to attend a public institution with no religious affiliation and actually take classes with other young people. I would be very surprised if they were.
