Aww, it's just good-natured ribbing between brand loyalists, happens in EVERY hobby. I always thought it was kind of funny to watch the Powerstroke crowd poke at the Cummins, and vice versa. Just the old "giving the guys the bizness" routine.
In the ancient days when I had a Corvette and went to places where sports car weenies hung out, this sort of brand-based chest thumping was already decades old. I still remember a limerick that's gotta be 40 years old by now...
There was a man from Boston,
who bought himself an Austin
Room for his a$$
and a gallon of gas
but his ***** hung out and he lost 'em.
Ahhh, the beauty of poetry! Now where's that pencil? I feel the muse...
The dejected Powerstroke owner,
was put afoot by a Ford design boner.
He closed the door with a groan,
and said, "I'm finally home!
"Thank God there was a Cummins in that loaner. "
