That's a rather extreme claim. I'd be careful about holding strong views on things you don't understand very well, especially on such a charged topic.
Not having a label for something makes it really difficult to talk about issues around that subject. How am I supposed to advocate for a group of people who have it rough, specifically for their skin color, if I can't use the term for their skin color?

But also note that the position of the AAA is not that racial inequality does not exist at all (and therefore should not be spoken of, as seems to be your position); their position is that it exists on social, rather than biological, grounds:
> we conclude that present-day inequalities between so-called "racial" groups are not consequences of their biological inheritance but products of historical and contemporary social, economic, educational, and political circumstances
