The first quote laid out a case using a narrative as a metaphor. It explicitly states its position, and as such is an appropriate use of a quote.
The second quote is entirely composed of appeals to emotion and its sole purpose is to ridicule the author of the first quote as well as any readers who might agree with it. As such it is not an appropriate response.
An appropriate response would have first established the premise of the first quote, then argued for or against it.

The age of an idea has no bearing on its quality. To an extent, humanity refines and builds on ideas over time but the basis of Western civilisation dates from Antiquity. To take your specific date range, this post is typed on a browser, operating system, machine, and global network that all date from ideas from the mid 20th century which themselves build on a few centuries of reasoning.
