This is a pretty deluded and ignorant take. America did not invent judging, preferring, or even just noticing people by their skin color. And I doubt 'normal dudes' self inserting into a story, or even just following the MC's story, are completely blind to him changing race or appearance significantly.
There are other HTML games here where the race is kept consistent, but the actor is changed, and that's still sometimes a little jarring, you notice. You can really appreciate when the developer goes the extra mile to hide that from the player as much as possible.
