indeed, there seems to be an echo in here !

Now as to the NPR story:
that headline is a quote taken from
remarks by the Simon & Schuster publishing house in the US.

So, for a start, the person who said this is not a fellow author
but someone at the top of the publishing business,
where celebrity as well as craft is important (for his bottom line),
and such is that person's bias.

A fellow author might indeed have an entirely different metaphor.

And different authors might have wildly different opinions.
Perhaps in a longer, more detailed piece of writing,
the Simon & Schuster talking head
could have justified his opinion, and his metaphor,
with a summary of
the history of 20th-century publishing of USA fiction?
Is there evidence, at some point in that century or even earlier,
of established publishers demonstrating
the prejudice of anti-semitism towards
authors who happened to be Jewish?
Without that evidence and history,
I don't know, myself, that Mr. Simon & Schuster makes any sense whatever.
