I was going to use the term middle ages but most people understand what “dark ages” refers to. Since my comment was actually how babies were treated during that time, and not about the correct usage of the name, I think you are a little over the top sending me a lecture on the correct terminology for the “dark ages”.
Most people understand the incorrect usage of the term with the bad connotation. I sent the correction to benefit all of mankind, not as a lecture to you.
