It’s very likely this is your classic Internet troll. After all, this person’s identity seems anonymous and unverifiable, which is why Disney wouldn’t have taken action. What can they do against someone if they don’t even work at their company?
If you have Asperger’s, then I can understand why you took it at face value and feel upset, but don’t let it bother you. People who spend this much energy trying to upset a random stranger online are just losers. Block him, move on and enjoy yourself.
