I didn't claim that Skyrim isn't an RPG, I said it's a bad one. The interaction with the world is so shallow that it hardly matters what role you assume. There's nearly no reactivity, other than a few audio cues. There's not a single memorable character with any depth in his/her personality - nor can you interact with characters in any meaningful way. The whole world stands still unless you do something (best example: the civil war that is supposed to be raging on, but nothing whatsoever happens). The storywriting for both main and side quests is a joke.
If that's what you think the RPG genre should involve into, okay. But I don't. I want complex, intriguing stories with meaningful decisions. I want memorable NPCs that have more purpose than waiting for you to fetch their quest. I want the world, characters and story to react to my choices and develop accordingly. And in all these aspects and more, that make a RPG good in my opinion, W1+W2 kick Skyrim's ass (as do many other games, because Skyrim does a very poor job at them).
