How is that insubstantial? Many do not realize that the west is also a purveyor of lots of propaganda and perhaps they should challenge what they hear from the western media about controversial China topics. That is a very valid point.

It would be substantial (that is, having substance) if the grandfather post perhaps included an example of how the western media screws up its China coverage. I have no doubt there are a lot to choose from.

"Oh the coverage is all wrong" is a pretty empty statement by itself.

So ask for an example to back it up rather than write the person off. Like I said, most posts here on HN are not backed up by references until they are asked for.

The President of the United States goes around saying CNN is "fake news", and you're trying to tell me that nobody challenges the Western news media.
