Taking "Made in America" too far?

This sign was displayed by a manufacturer at RMAF:





So what do you think? Does it cross the line?

As an American Company, it should be about promoting American Craftmanship, Ingenuity, and Quality. Think pro-American, but not degrade or demote others. The sign absolutely promotes hate in my opinion.
While on the topic, buying American shouldn't be a given, it should be earned through competing in technological prowess, quality, and/or cost. (e.g. If the object could do the task better, and last 3~4 times longer, then I would be willing to pay double). Okay I'm done.
