We make the distinctions that are important to us, that doesn't meant that we aren't capable of making finer distinctions if we need to

I sometimes get the feeling that people in such debates don't understand the concept of feedback loops. It is entirely all right for language to influence culture and to be influenced by it at the same time. And it's not even that mind-blowing or difficult to reason about, one just needs to step one level higher on the ladder of abstraction.
In English, if you casually ask the color of the sky or the color you would use for water on a map, most people will simply say "blue" even though they could probably detect hue difference if presented printed samples of the two. Accordingly, I think most English speakers would say Yes if casually asked whether the sky is the same color as water on a map. But is that the same response and reasoning you would get if you asked a speaker of a language that doesn't distinguish between blue and green whether the sky and leaves are the same color?
If I see a Chinese wearing what I call "aqua-green" clothing, I often ask them "What color sweater are you wearing, blue or green?" They always answer "blue".
True, but just to be clear: In the first link in the article it's shown how people speaking languages with no blue/green distinction are significantly slower at selecting the 'odd one out' when given a set of blue shapes and one green shape. Furthermore, this effect is only significant in their right visual field, whose images are processed by the left (more language adept) part of the brain.
