We've known for some time now that Derick Dillard is not Jim Bob Duggar's favorite son-in-law.
In fact, it's been said that Jim Bob flat-out doesn't like Derick -- and frankly, it's not hard to see why.
After all, other than Josh, no one in the Duggar clan has done more to compromise the family business than Derick.
The clearest evidence of Derick's ineptitude is the fact that he got fired from Counting On and convinced his wife, Jill Duggar, to quit the show as a gesture of solidarity.
But leaving his family without a source of income was just the first in a long line of eff-ups for Derick.
From there, Derick's bigoted social media tirades continued unabated, as he attacked other TLC stars such as Jazz Jennings ad Nate Berkus in the sort or ignorant tirades for which he's become famous.
Jim Bob and company probably didn't object to the belief system behind Derick's unhinged rants, but the Duggars likely took issue with the public nature of his hate speech.
After all, not unlike the evangelical church that seems to have served as his business model, JB built an empire that's based on strict adherence to a set of mostly arbitrary rules.
These days, Jim Bob's offspring -- particularly his daughters -- are flouting his guidelines left and right, and the patriarch reportedly blames the men they married.
Jinger Duggar began wearing pants in defiance of the family dress code after she was granted permission by her husband, Jeremy Vuolo.
And now, Jill Duggar is allowing her kids to enjoy secular entertainment -- a massive no-no in the Duggars' world.
And not surprisingly, it seems the Duggars believe Derick is squarely to blame.
And it seems D-Dill may have just confirmed their suspicions on social media.
Earlier this week, a fan asked Derick, "Why don’t you guys get a TV?”
“How do you know we don’t have one?” Derick replied.
If you're a longtime Counting On fan, then you're probably already aware that the Duggars grew up in a house without television.
In recent months, Jill and Derick have taken flak for allowing their children access to such popular children's characters as Peppa the Pig.
That may seem like just about the most innocent thing imaginable, but the Duggars are of the belief that all children's entertainment that all children's entertainment should have to do with fire and brimstone.
That way, kids like Henry and Spurgeon will understand why their dad is going to hell.
