Not only that, but there tends to be a lot of handwaving about how “race” is used or defined. For example, the OP speaks of Asian representation, yet has a content tag of “race”. But Asian is not a race, it is a region. Mongoloid people are a race in Asia - yet they are not exclusive to the region, nor it to them.
It seems ironic that many progressives are quick to tell people that it is worth making the effort to use correct terms to avoid offending people, that thinking and minding what you say is a small and worthwhile tradeoff to make for the resulting benefits to society. Yet if you point out to them that referring to anti-Mexican or anti-Islam as “racism” is very sloppy rhetoric, they often fall back into the same defensive postures that typical conservatives do. That it is pedantry, frivolous semantics, that they are being expected to change their habits to please an annoying interlocutor. Sounds familiar, doesn’t it?
People often defensively play that off as criticizing the loose use of the terms is somehow an implication that the phenomena are somehow not a problem, rather than being a conscientious observation that we could make a better argument against what we acknowledge as being a problem. Or at the very least that there are multiple productive ways to frame and act upon it.
