How is kindness a bad thing? I thought that was universally agreed to be a good message to have in a piece of media. I guess the excuse is they don’t want media to have messages at all but like, how would you even have a movie where the hero has no values that they stand for?
If they’re okay with immigrants who didn’t come by choice, then all the children who were brought to America illegally by their parents should be allowed to stay and everyone born in America should be allowed to stay citizens.
As for Superman not looking like an immigrant, it is actually a big coincidence in-universe that he happens to look like a white human. There’s no Europe on Krypton.
Now I want an alternate-universe Superman who happens to be black, and lands in racist-as-hell-ville in the rural USA.
