It's resembling an attack of the author, instead of the authors ideas, aka a form of ad hominem. So it's kinda ironic to say the author adds nothing while simultaneously adding nothing with a non sequitur.
I know nothing about the author outside of this article and I can't remember ever reading anything else she wrote. The author may be a perfectly virtuous person - but knowing that may actually bias my review/critique.
For example, this is actually a story about a mother worried about her child. I really appreciate that! What I don't appreciate is someone using that to present unsupported positions.
I am attacking the piece that she wrote and it's because I don't think it was a good piece.
