I don't normally post here, but have been lurking for the last few days to read all of your thoughtful opinions on this. I thought I'd share some discussions I've been monitoring over the last few days.
I participate in an active online community on a subject totally unrelated to TV or anything Duggar related, and this scandal has been a hot topic of discussion. Without exception, the members of that group who are posting on the subject now want the show off the air (that wasn't the case when it first broke, but opinions have changed as more information has come to light). This is a very diverse collection of people - some secular, some very religious. Some liberal, some conservative. Many people posting are those who casually watched the show and/or followed the Duggars in some fashion via People, Today, etc., and admired their wholesome image and well-behaved children. They are now reading all about Gothard, ATI, blanket training, etc. and are absolutely horrified that they bought into any of it. They're taking it like they were personally lied to by TLC and the Duggars, and they're angry about it. They are all saying they won't watch the show again if it stays on the air.
I know it's a small sampling, but I found it interesting to see what "normal" people are thinking about the whole thing. Not leg humpers, not Duggar haters, not Twitter trolls - just regular people. If this is any indication, it doesn't bode well for the show.
