The good news is it’s just the US parks, I can go on DCL or go to one of the international parks and still get the Disney idealism I used to get here.
“Self expression” via tattoos, bright hair colors, unkept beards, lack of ironing, etc is an American trait that hasn’t caught on overseas (or on the seas) yet.
I don’t think this is Disney embracing individuality, it’s Disney adapting to the US hiring pool, if there was still an ample pool of clean cut applicants I don’t think we’d be seeing tats and unique hair. They adapted to what’s available, not inclusivity .
I don't think you've ever been to the French parks then. The "Disney Look" went against French culture and French law, so they had to adapt it. The Disney Look of the US parks now is closer to the Disney Look of the French parks.
