I did read your post...you're just getting more and more off the mark with all of the points you're trying to make. Harry Potter is so much bigger than what you're dismissing it as.
I was a Star Wars fan from the very beginning, and I remember how crazy it was back then. When we were waiting on line to see the latest Harry Potter film, my sister and I started comparing it to when our mom took us to see Return of the Jedi on opening day because the level of excitement was just as high, as was the line. We saw these spastic kids in talking about Harry Potter the same way me and my friends how Darth Vader could possibly be Luke's father when we were their age.
Harry Potter appeals to all ages too. I saw plenty of adults when I was at the midnight party for the last book. On that line before the last movie, there were college professors standing behind us discussing Book 7 theories. The NY Times was forced to create a children's best-seller list because publishers complained that the Potter books were taking up so many places for so long on the regular adult best-seller list.
As far as Disney, Lucas owns Star Wars, he was the one who allowed the ride to be built, it wasn't exclusively a Fox thing. He grew up a lifelong Disneyland fan, the ride was a perfect fit. I've read about one of the Potter rides that's coming, and it's going to be pretty cool.
Having read all 7 books, and knowing how bloody epic the 7th film has the potential to be, we still don't know exactly what the lasting impact will be. It hasn't had time to catch up to Star Wars yet, but it's well on its way.
