With this skimming comes a side-effect. If you do not very explicitly state your meaning on every key point you write, with detail and in several clauses apiece, the reader doesn't find enough key words to catch their eye. They skip right over major points.
What is the result?
The reader misses something vital you already answered, then moves on to life's next shiny bauble. You never get past the reader's filter. The reader never registers the validity of your point. Or worse, they dismiss your observation as ill-considered because they miss the fact that you *did* consider key alternatives.

In today's world of filter bubbles and custom-tailored content, understanding the author's meaning rather than one's own predisposed opinion is often considered an imposition.
Don't be afraid. Impose.
