Is our perspective any more misguided or arrogant than the perspective of a European, or a Chinese person? Because if it is, then we can all stop complaining about Europe and China right? Because our perspectives are all just misguided arrogance.
Now I'm not saying that our perspective on foreign nations is necessarily "right" and "factual". I'm only saying that our perspective is certainly no more "wrong" than any other perspective. Perspectives are not objective realities, but they do become subjective realities for the people who hold them. (Read, "all of us".)
So here's the thing, whether or not those subjective realities are "misguided" or "arrogant" is not really a function of where the holder of the subjective reality grew up, it's a function of a lot of other factors unrelated to national origin. Everyone will have a perspective any given issue. Everyone may even have different perspectives on different issues, but whether or not one perspective is more valuable than another is usually not a function of things like citizenship. The relative value of different perspectives usually turns more on factors such as power and influence; sometimes on other factors like intelligence, and thoughtfulness. Outside of maybe power, rarely do these factors respect national borders.
If you want to discuss your perspectives on life with other people that's fine. (Actually I think it's admirable even.) There just shouldn't be the expectation that anyone else has to sit down and discuss their perspectives on life with you.
Other than that though, I think we're in agreement. Different people can have different perspectives that become subjective realities, but are usually not even close to being objective realities. People have the freedom to discuss, or ignore, other perspectives at their sole discretion. Thereby fulfilling the promise, and conveying to us the benefits, of freedom of thought.
