I drive a Toyota Tacoma pickup, why does everyone glare at me with dirty looks?

I live in a small town in Montana. When it comes to the truck I drive, I seem to be the black sheep of the herd. It's a 2004 Toyota Tacoma 4x4 with 4 doors, a short bed. I love my truck, it's good on gas, and has never let me down. But many of the locals seem to think otherwise. I get angry, hateful glares from guys driving big domestic trucks like diesel duallys and what not. They have these huge gas guzzling trucks which may work for them, but frankly, I don't need or want something that large as my daily driver. I like my small truck better. When people ask me what I drive, they get all upset and say things like "drive american!" or "you aren't very patriotic for driving Jap crap junk like that".

So, why do people hate my Toyota so much? I checked where it was made and according to the sticker on the door, it was assembled in San Antonio Texas and sold in the US. Wouldn't that make it pretty American of me to buy something that employed American workers to build and was sold through an American dealership? I guess I don't get what all the hate is about. Most American trucks are assembled in Mexico and Canada from what I read meanwhile most Toyotas and Hondas are made right here employing the desperate American workforce.

So why all the hate from these guys driving big Fords, Dodge, and Chevy trucks?
