It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so.-Mark Twain
You can't wake a person who is pretending to be asleep.
Nobody is really or purely a "redneck" or a "boorish dude/girl" ; that's a stereotype.
Saying that moody types (low serotonin) are all boorish is like saying that tough-minded types (moderate serotonin) are all machines. I'm not a machine.
But in fact, most 468's I encountered in class liked to play boorish dudes/girls. Mainly, there was an ILI-4 dude that liked to create or get involved to random conflicts. Yes. For some time interval, the "bully" of that school was actually E4. No joke. I mean, if you have a bad mood, you're likely to overcompensate a low drive.
I disagree, there are people that are as redneck as you could imagine...lol
Most of my younger years were in the hills of Tennessee, it is a fact that there are many people exactly like what you posted. Then again, it's also a fact that many of the people that would be considered "redneck" are also great people... many of whom like moster trucks, tractor pulls, rodeos, and drinkin beer and driving around town...lol
