I was just thinking about it more & made an interesting comparison in my head; what about actors & actresses? Their job is to step into the role in which they are playing, they become that character through costume, bahavior, mannerisms, etc. When they’re on Broadway, television, on film, etc. they most often leave any religious symbols behind to transform into their character for the show.
Disney has it organized so that employees (cast members) ARE playing a role, “on stage” as they refer to it, and sometimes mannerisms & even accents are used to tranform into that role (Haunted Mansion CMs, ToT CMs, etc), costumes are DEFINATELY being utilized as part of the “show.”
If my job involved being a “cast member” for anything, where on “stage” I became whatever my costume was intending to convey I wouldn’t expect to bring my own pieces of physically identity into that ‘role’ unless it was accepted as part of the show.
Seeing these religious items would never be offensive to me, especially since I live somewhere where I see almost every ethnicity & religious affiliation all the time but I get it, in this case.
