Disney allows the Gay Day organizers to use the jealously guarded trademarks of the Mickey Mouse profile and Mickey Mouse ‘Mouse Ears’ without legal challenge year-after-year.
Given that if I produced an image with those trademarks I’d be almost instantly sued and ordered to cease and desist I can only and reasonably conclude the the Disney Corporations’ deafening silence in this matter is an active endorsement.
Is this independently or in fan capacity?
Usually content producers wink benignly at nonprofit fan derivative works, and that’s how this is viewed, I think. Granted that if Disney had a more “normal” morality it would be bothered by the association. I don’t think any Christian group has done anything similar (what would Mickey do, carry a flag with a cross on it?)
