Why the Sneeches was an allegory...
The Sneeches was an allegory because it was giving the message that there is no one group of people, or anyone, who is better than someone else. Everyone is equal and everyone should be treated as such. The moral lesson is also that no matter how much we try and change ourselves, in the end we will always end up being the same person. Also no matter how much we try and hide or change who we are so we can blend and mix with other people, we can only change our appearance and if they didn't accept you in the first place, chances are when you change they will still ignore you.
