In all the action items I've seen posted here, this very important one seems to be getting missed. You can call Disney Corporate directly and you will speak to a person who will in turn put you through to a comment line. I politely gave her a piece of my mind and then left my recorded one on the comment line as well.
The Number is: 1-818-560-1000
I just left a message stating that I have visited Disney's theme park in Orlando in the past and planned to do so again, but that if they do not pull the plug on this completely inaccurate piece of trash about 9/11 I will never visit their parks or purchase any of their products again.
My message alone may not do much. 10 or 20 Thousand messages like that, however, may get through to them. Happy calling!
