Title of article, when I view it, is
A New Study Details a Startling Air Pollution Racial Gap
https://www.motherjones.com/environment/2014/04/air-pollution-racial-disparities-nitrogen-dioxide/
So, did OP change title, or did the article change title in the decade since it was posted?
But yeah — the premise is ridiculous only if you deny systemic racism. If you accept that, then (awkward “title” notwithstanding…) this is pretty clearly the case: economic stratification isn’t just “my home is bigger than yours,” it’s “my home is further from the freeway than yours” or, if you like, “living in my home is healthier than living in your home.”
Not all honorable fighting is done with a bat’leth.
