On your first paragraph, pondering whether sucrose breaks down into fructose and glucose immediately: No, it doesn't. HFCS makes sugars available to the bloodstream sooner, causing larger swings in overall blood sugar levels. Additionally, this study covers rats which were given strict diets; the idea that HFCS made them fatter because they ate more food is not borne out based on the experiment's premises.
Second paragraph: Irrelevant. Honey is not being discussed here. Additionally, you contradict yourself by noting (correctly) that HFCS is not half-and-half fructose and glucose, like sucrose.
Third paragraph: Inverted appeal to authority. You dismiss the information that science makes available, and then put your own opinion up for offering as if it is informed and accurate. You further confuse the issue by putting a well-accepted opinion (the diets of the USA are overly rich in sugars) next to a dismissal of this study.
Fourth paragraph: A delightful strawman, substituting artificial sweeteners for table sugar.
Fifth: More ignorance of the general study of nutrition, with a sweeping statement that is obviously true and yet completely uninformative.
