The "This season has the lowest toxicity" claim ; Is it sourced?

Having been reading forums most of my life, since back during the era of ancient internet.... I am very skeptical of claims made by anyone on the internet, however... in the back of my proverbial mind I remember someone with authority making the statement that indeed, we are playing in an era with the lowest toxicity that has ever been observed.

Now, did I hallucinate such a thing or is it true? I attempted some google searches but turned up nothing.
