What if the painter meant a 6 but an entire culture, entire nations of people have be interpreting it as a 9. For hundreds of years this has been known as "the place with the big 9." The author's interpretation of the meme is stupid. Human-decided things like this do not have objective right and wrong the same way that facts about the physical world do.

The painter made a single sentence to make a simple point. The next person replied with two paragraphs about how they interpreted a much more complicated point, and in doing so missed their own point.
