Another user already posted this link. Here's tons of evidence and someone wondering why we've ignored that evidence for so long.
Secondly, I disagree with your assessment of anything I said as "vitriol". If it's vitriol to call someone's statement ignorant or point out that they're committing the very act they're complaining about through that ignorance, then I would claim that you're confusing "vitriol" with "directness".
