OK so you are willing to state that Disney has never sued a non-commercial entity for using their name, right?
C'mon. Be a man. Say "Yes Hank. Disney can't sue someone for using their name to promote their event". You can do it.
My guess is that you KNOW they can and you don't want to admit it. Disney has sued lots of people for using their name without permission.
Do you have any sources? Or am I supposed to take your word for it?
Disney has sued day-care centers for using unauthorized Disney trademarks (Mickey Mouse and Goofy). This is because if Disney fails to uphold their trademark, they relenquish that trademark forever.
However, if you say or imply that Disney is sponsoring, backing or promoting YOUR event; then you have violated the law. The gay groups realize this, thus the phrasing used for Disney Gay Days is carefully worded, and checked out by both the Disney legal department, as well as the individual groups.
For example, I can say "The Arlington, South Dakota class reunion of 1979 will be held at Walt Disney World. Come join us for 'Cardinal Days' at Walt Disney World ...."
However, I cannot say "Walt DisneyWorld is proud to announce 'Cardinal Days' on (date) for the Arlington, South Dakota High School class of 1979.
There's a big difference, so please provide an example to what you are referring to. One method says a group is meeting somewhere, the other method implies that the park is sponsoring, promoting or supporting.
