Based on my limited experience, people who think grammar Nazis are annoying shouldn't be suspected of being too intelligent.
A great example is "red-head scarf"; what you read is "(read head) scarf" what it means is "red (head scarf)". Granted, it makes the wording unnecessarily complicated, but it's probably grammatically correct.
That’s not the only nor the biggest nit you can pick with this essay.
