From the article :

For one thing, it’s not even clear that the claim that Chinese women have small fingers is even true. Research on global hand size is lacking, but one study found that the average Chinese person has a hand size approximately equal to that of the average German. An analysis of hand size around the world, though it didn’t include China, found that even the largest average differences in women’s hand size between countries was negligible.

This is not the dubious claim.

It is dubious.

Follow your own advice then, you’ll learn that it’s the role of the journalist to qualify wrong and offensive statements reported, or it is implied that the journalist approves of the position.
