I do understand that interpretation, although this is not just a feature of AI generated memes. Most memes posted here use only white characters or have western opinionated bias although I don’t see anyone having issues with that, it’s only when it’s AI generated.

The person who created this meme had the option to make the characters in the meme to of various ethnicities but didn’t. It’s not particularly difficult to prompt AI’s in specific ways so it reveals your creative vision rather than allowing the AI to make the decisions for you.
