^^ I dunno, based on the content of the rest of the blog and the followups they posted, I think it might actually be real. That, or the person running it is very dedicated troll.
To be fair to the idiot, they're using it as an example of how cultural appropriation is supposedly normalized in fiction, rather than an actual example of appropriation. It's still stupid as hell, though, and rather insulting for them to put it up alongside genuine cases of racism and stereotyping in the media. Adapting to norms in a new region when relocating (particularly when you're encouraged to do so by the people in said region) in order to gain acceptance is basically the exact opposite of cultural misappropriation.
