You just witnessed modern US propaganda in action. We are all constantly barraged by messages about "if you look non-white you must be oppressed, poor thing". And because it is constant it is making people perform snap judgements rather than actually think.

Of course someone from Uzbekistan is quite different from an an American with a vaguely Asian looking face, both culturally and economically. Any yet the parent comment author's brain automatically filed them in the same bucket. This kind of automatic thinking is exactly how propaganda works.
