This is what happens when you only talk to like-minded people and live in a bubble. There are still plenty of people I know who would reject foreign ideas simply because "pshaw. We can [do that/do it] better."

I mean I literally worked with a guy who got annoyed at the harmonized power cord I bought because it used IEC wire colors and "This is America where we use American wire colors, not that European shit. I taped the leads red white and blue!"
