you listen to Ralph under his stereotypical “good old boys” accent, he really has that giveaway drawl of a dumbo.
Hey not everybody with a "good ol' boy" accent is dumb, ya'll proliferating some damn Yankee slander there, boah.

It's arguable wether Ralph is even a good ol' boy to begin with, the Ralphs are a family of carpetbaggers that fought for the Union, although I guess they've lived South of the Mason Dixon for long enough by now. Southern is a state of mind anyway.
I don't think Pat is that low iQ or dumb in the sense of retarded, he's articulate and sounds intelligent enough in interviews, Pats problem I think is more something Richard Spencer said to Sargon "your problem is you are just not as intelligent as you think you are, and thats a hard place to be." Pats not a retard, but he like all narcissists he has a vastly inflated opinion of himself, to Pat, Patrick is always the most intelligent person in the room. If he was at dinner with Nikola Tesla, Stephen Hawking, and Eratosthenes, Pat would likely
still be a condescending prick and do that bullshit he does if any of them dared to contradict him, no matter what subject is currently being discussed, Pat is the expert, no matter what situation he finds himself in, Pat has the high ground, and thats the worst thing about people like Pat, he's so convinced of his own intelligence and his own superiority he has neither the inclination nor the will to learn. If he was as smart as he thinks he is it would still be a problem, because everyone can benefit by learning and improving, but Pat is below average at best, which makes his arrogance and unseemly condescension even more of a handicap for him.
TLDR - Pat is handicapped, not retarded.
