You read too much into why I mentioned "foreigner". I actually wanted to ask whether people consider the video that I posted above, which is made by an actual foreigner (as a fact, not as an insinuation of anything more) can be considered an honest opinion.
I also used the word "valid" as a shorthand for "an opinion that deserves to be heard and considered, rather than downvoted or dismissed", for the lack of a better term.
To point back to that comment, Chinese living in China have just as much a right to have opinions on it, and so do Americans living in America, but neither of their opinions are worth half as much as people living in Hong Kong. As long as they're representing themselves honestly (as Chinese or Americans, living in their respective countries), they've still got honest opinions, even if their opinions don't matter as much as the ones of people living in Hong Kong.
