I've been drinking fruits, fruit juices and smoothies instead of most other carbs for a year now and I feel great without being fat. It's just about calories.

It makes a great argument that high-fructose corn syrup might be single handily the cause of the explosion in obesity in the USA in the last two decades.
You dismiss the recording of a university class made by a Ph.D in Endocrinology that worked for 20+ years against the whole industry (which shows resilience and belief).
On the other hand you suggest to read articles on 3 websites that looks scammy at best?
I feel insulted.
The guy saying Lustig is "wrong" was just full of it and I called him on that.
And I'm not saying he's wrong, I'm saying HFCS is indeed toxic, not sugar and fructose (proven by lots of studies made by PhDs with years of experience). So he's partially right.
A calorie isn't a calorie. The impact that 100 calories of vodka has on your body vs, say, 100 calories of Kale is significant. The body uses different strategies to break down different types of molecules. There can be toxins. There can be impact on the gut flora. Not to mention the impact that these all have on the feeling of "fullness" (which the article mentions).
Metabolism plays a very important role and even if it's really complex, fructose is very good for the metabolism (glucose is inferior in that regard).
