The dating thing...in the last special didn't they talk about that the oldest boy would soon be allowed to have supervised and fully chaperoned "dates?" I seem to recall them saying that the kids would have any time alone with anyone they were dating though...everything would be chaperoned. I can not imagine NEVER having spent time alone with someone before marriage. I can get the no sex before marriage thing but it just baffles me that you would not even be allowed to sit and chat in your parents living room alone with your future spouse.
A lot of things baffle me about them though. I don't think the kids are being abused at all but I also don't think they are doing the kids any favors by not exposing them to more of the world. You can still monitor what they are exposed to and make sure that it is appropriate but allow them to be exposed to more out there. It bothered me that the girls didn't seem to realize that they had options beyond repeating their mother's life choices. If they are aware of other options and know that Mom and Dad will support them if they want to be a doctor etc. but they still choose to be a SAHM and pop out 10+ kids, then that's fine. It just seemed like they weren't really given options beyond wife and mother. I'm a SAHM myself and for years swore up and down I would never do this! I have a masters degree and left a professional career for this...but I did it because it was my choice, not because anyone, my husband included, expected me to.
As for the hugs thing...they did show some affection, the Mom reading to the girls, she said, very sincerely, "I love you!" to the kids as she turned out the light, they were kissing the baby goodnight etc. They may not be a very physically affectionate family though. I know a few fundamentalist families who do not "do the hug thing" as they find it inappropriate but they are loving families. That may be where the Duggar's are. That's one of those vastly different from my family where hugs and kisses are given freely all the time and DH I show affection not just to the kids but to each other in front of the kids but if that is what the kids are used to, chances are they don't find it odd. That would definitely be the case if they are only socialized with other families who are of the same mindset. They wouldn't necissarily be aware that other families are more physically affectionate. Of course there is equal chance that hugs are freely given but they weren't shown on camera. Even if they have a strange (by my way of thinking) way of showing it, I do think they love all the kids.
Their life is definitely a bit odd (again, by my way of thinking) and not something I would choose for myself or my kids (as in I would find it odd if one of my kids decided to marry in to that family) but I guess the way I see it is that it's not my place to judge them. There are things I think are legit concerns with a family that size not the least of which is each child getting quality individual attention/time with Mom and Dad. That is something I am struggling with here as we were recently surprised to find out baby #3 is on the way to our home. I have no doubt in our ability to love another but I worry how the new division of time and attention will affect the 2 we love so much already. I can't even begin to fathom that with 16 children!
DH watched part of the show with me and said "with 10+ kids, how on earth do the find the time and energy to make more???" I pointed out their schedule and extreeme organization and said I'm sure it's scheduled just like everything else! Penciled in after 9 PM Bible time w/ Dad and before Mom gets up to change out the laundry.
