Native american indians?

[Ulvenok]

It's common knowledge Tolkien modeled arda on our world, shire roughly being where Tolkien grew up. This has lead to many thinking he was racist and maybe he was but this isn't why I made this topic. Valinor would then be america would it not and the native american indians lived in harmony with nature, qualities I'm sure Toklien would approve of. Is it possible that Tolkien had a certain liking for the native american culture and thought of them consciously when he created valinor and the elven race?

If one would imagine Tolkien to be eru which in a way he is, then could the destruction of Numenor be some kind of metaphor for Tolkien's dislike for how Europe treated the native american indians and about industrialization in general. I know he has said he doesn't approve of his work being perceived as allegorical, but it sure makes sense. His love for nature is apparent through all of his work and the native americans are very much alike to the elves except they're blonde. (racist) just kidding
