Mendo, you’re absolutely right that the author is biased. Fortunately, he also provides a plethora of data to support many of his claims. You also mention how biased your own take on all of this is, which is fine, and I appreciate your honesty. Just look through to see if there are places where you can provide more evidence as well. Your voice is so strong as a writer, that splashes of data and evidence could provide an even greater impact.
