Homophobia
Is it really surprising that the Duggar family is homophobic? Just look at their history! Well, everything was going swimmingly until Michelle discovered that one of the production crew members was gay. This upset Michelle, and TLC had to remove the guy from the set and put him in another filming crew.
All of this was on the down-low, so the network paid the guy big bucks to keep his mouth shut. Even though the current production crew is pretty tight-knit with the Duggars, they do have to walk on eggshells when speaking with them. Remember: the Duggar family comes first!
