That's a misreading of the term in the same way saying that the phrase 'black lives matter' imply white lives don't matter

The point is that this type of environmental pollution only is allowed to happen in poor areas that are disproportionately black because of decades of systemic racism like red lining.

If that concept makes you uncomfortable, that's a good thing, it should. But you should resist the urge to deny the existence of ideas that are inconvenient

What's uncomfortable is not the racism claim, but that the argument is merely a conjecture. It's lazy and dishonest. More importantly, this line of argument tends to shut down intelligent conversation, which this forum is about.
