Having met Mr. Huffman I can say that he is a highly intelligent and educated man who would be completely at home at a demolition derby.
The first time I was called "an educated redneck" was at Ranger school. Having grown up out in the sticks I picked up all the usual tricks, sharpening knives and tools (although I've never really got the knack of hand sharpening a wood saw), operating heavy equipment (tractor, bulldozer, forklift), and the usual sort of farm work. I really was a Boy Scout once upon a time.
None of that stopped me from going to college, and it has helped me immensely in my military career.
You know who else could be described as an "educated redneck"? Most of the founding fathers. George Washington was a farmer. Very few of our founding fathers were "urban elite".
So tyrants beware, there are still "educated rednecks" who cherish liberty living among us. Lord Baden-Powell lamented the decline in the fitness of British youth to military service over a hundred years ago and started the Boy Scouts to help correct the deficiency. Redneck boys simply call it "recreation".
