It isn't about blame. Calories in/calories out is what we know influences weight. If you have some significant insight to contribute there, great! If not, please don't marginalise proper insight and factual knowledge by implying the person in question needs to feel bad for telling you.

Yet, weirdly enough, if a food item had all of those qualities except being calorically dense it wouldn't make people fat. Everyone one of those factors are things that lead to over eating, when paired with calorically dense you end up with the chronic over nutrition mentioned in the title.

Yes, but if it were missing the other factors and was only calorically dense, it also wouldn't make people fat.

That's like saying if cocaine made you feel like shit people wouldn't be able to get high on it. The issue isn't the food, it's the individual's brain.

It will make them fat if they eat it. Which is the very assertion you were disputing. The reasons why they might eat it have nothing to do with whether over eating makes you fat or not.
