We probably don't need to tell you that many, many things are banned in the Duggar family.
Pre-marital physical contact, certain types of clothing, any food that won't instantly harden your arteries and/or doesn't include Tater Tots as a main ingredient ... the list goes on and on.
High on the Jim Bob's list of harmless diversions that'll earn you a pitchfork where the sun don't shine in the afterlife is secular entertainment.
In JB's mind, there's one reason and one reason only to write a song -- and that's to praise Jesus.
In fact, we're pretty sure that's Jim Bob's only approved reason for doing anything.
So you can imagine the patriarch's chagrin upon learning that his kids have been tuning their radios to 66.6 Satan FM.
It started with the revelation that Jana Duggar enjoys listening to Michael Buble.
We literally can't think of anything less dangerous than Jana Duggar rocking out to Michael Buble, but like we said, Jim Bob makes Ned Flanders look like Ozzy Osbourne.
Anyway, from there, things escalated rapidly.
Next thing we knew Jill Duggar and Derick Dillard were taking their kids to see Toy Story 4, which -- if we recall -- doesn't have a single crucifixion scene in it.
Now, JB's worst nightmare has come to life, as Derick has expressed a fondness for the hippity-hop.
D-Dilly posted the above photo this week, along with the following caption:
"I love it when they call me big papa... ha love hangin with these two, even if it might not always seem the most productive.
"It’ll pay off in the end. I love them and how inquisitive they always are about the world around them."
Again, incredibly innocuous -- until you consider the fact that Derick's opening line is a reference to a song by the Notorious B.I.G., a man who is literally the exact opposite of Jim Bob Duggar.
Believe it or not, this isn't the first time that a member of the whitest, most rural family on the planet has expressed an affection for a genre of music that was born in black urban communities.
Jessa Duggar's husband Ben Seewald loves hip hop and he even interviewed Christian rappers on his short-lived YouTube series.
Although come to think of it, Jim Bob's disapproval of his content may have been part of the reason that Ben's show didn't last very long.
Better be careful, Der!
