F'ing Chevy

How can someone say "he/she is a Ford person"
It doesn't make sense.
Maybe you have a Ford car, and you like it now, and that's fine,
but Ford is the shittiest car company, IN THE WORLD,
surly everyone knows that, even those with Ford cars.
saying you're a Ford person means you like shitty cheap cars.
I don't get it.

I really like Natty Ice.
