Your dad sounds a lot like mine. My dad served in the Army during WWII, Korean, and Vietnam. Absolutely hated Asians ( as we call them today). He forbid all of his kids from ever buying their cars.
I was about 8 when my Dad sent me in to the Hardware Store to get some Hack Saw Blades, I came out gave him the change and the blades (made in Japan), he sent me right back in with the change and told me to tell the man I wanted Made in the USA blades.
(Ol Dad was ticked and that did not happen very often)
