This entire argument seems to revolve around the idea of "colorblindness". It basically roots itself in the idea that race shouldn't matter and therefore it doesn't matter. By stating that race and skin color are meaningless, you lay blame on anyone who acknowledges their existence. However, this mindset does not mirror reality. In reality, skin color and race are not socially meaningless. There are a number of stereotypes and tropes which have a deep history with their ties to race and racial divides are still very much real within socieity.
I think one of the clearest ways to picture this idea is to recall the black minstrel. Black minstrel characters are often considered to be synonymous with the use of blackface, but to leave them at that is doing a disservice to the idea. Basically, the black minstrel is a character used to imply (or outright state) that black people are stupid, happy-go-lucky idiots, essentially putting forth an air of racial superiority while diminishing the struggles of the african american community (especially in the 1800s), through the repetitive use of a character fitting the same archetype.
To state that race is irrelevant to a character is to state that there is nothing wrong with the black minstrel character. There is nothing wrong with a stupid character. There is nothing wrong with a black character. There is nothing individually wrong about any of these traits, however, it is the utilization of the traits in conjunction and in repetition which creates the stereotype and it is this combination which has its societal impacts. Because the color of a character's skin does matter in fiction because it still holds societal importance in real life.
The reason the Asian Math Whiz character exists is because it is a stereotype placed on Asians in real life. As such, the utilization of this stereotype is not only lazily falling upon stereotypes, but potentially doing harm by furthering a stereotype. Yes, a Black Math Whiz character would be a different character, because it does not similarly call upon tired cliches and it does not have the same societal impact of reinforcing stereotypes. If anything, this character would be going against stereotypes.
Now, all of that isn't to say that a certain character type cannot be done. As the author of the original article states, this character was actually handled quite well. However, it does imply that more needs to be done with a character in order to establish them as more than "another".
In conclusion, the argument that "mentioning that race is a component of many stereotypes is racist", might be true in a utopia where race had no societal importance, but in reality, it is simply ignorant to the differences and struggles of the societal experiences of different racial groups.
