I think you are almost correct. A victim of racism or an advocate for a victim of racism is not being racist for calling out the racism. However, a person blaming racism without evidence and where it does not exist is indeed engaging in racism themselves, because it exposes their own notions of the group they are attacking. Calling out "racism" is not automatically a sainted argument above reproach. This is a general statement, not directed at the case in the article.
