I think you're completely missing the point. Graydon isn't talking about the receipt of constructive criticism. This is literally the first sentence:
"Each now and then someone on the internet decides to write a screed or rant in a comment section about how Rust is a terrible thing full of mistakes and stupidity, and they cannot wait for it to die soon enough."
He's also not talking about "ignoring" criticism, hurtful or otherwise. This entire post is his take on how to respond calmly to irrational antipathy.
Yeah, I did read the article. I only dedicated one line to the title. On recollection maybe he's attempting to click-bait the people who would agree with the title (and hence need to read the article).
