I base this suggestion on a sample I visited:

Let me break down this page: A TITLE IN ANGRY ALL CAPS. A paragraph stating the misconception. Three paragraphs of ranting about the badness of the misconception without actually explaining what is bad about it. A list of sub-misconceptions, again without explanation, but with a helpful WRONG next to each one, in case you needed more shouting. Then another paragraph of throat-clearing. Then, finally, some explanation.
Everyone gets enraged by idiots at one time or another. But capturing that rage in print is rarely productive. Rage tends to be repetitive and soon becomes grating. Fortunately, there is good stuff here; it just needs editing and rewriting, possibly over a nice drink in a relaxing place.
