No, they don't say that. You came up with that racist anecdote all by yourself.
That's all anyone needs to know.
There’s some truth to that, it’s cause they still look more European “white” higher in the food chain, whether more educated, wealthy, classy, etc of course not all thinks with this mindset but a lot do
Why you think Spanish/Mexican tv anchors/reporters look less mestizo/Aztec and more European white
It happens all over the world, nothing new, Argentineans will feel superior to Mexicans/central Americans, Japanese, Chinese and Koreans will feel the same about southeast Asians, etc
