Like those blobfishes that look grotesque when you take them out of the water.
An Indian in the wild would not look very different from any other primitive people (Papuans, etc.)
But if you give them Western clothes and language it looks completely weird, like some sort of sick mockery.
Same thing with Africans. You see some African wearing traditional clothing, doing weird dances, etc. and while it might look a bit alien, it doesn't really repulse you. Because it feels like they are where they belong.
But an African speaking bix nood in public transport in a Western city is a disgusting sight.
