Yes, I read it. He's misusing the word racism as defined in several dictionaries. See the Wikipedia article on "racism" for examples. (Yes, I saw your comment in Wikipedia elsewhere, where you quoted a definition from it...read farther in the Wikipedia article, as there are several other in that same article that disagree with the one you cite, including ones from three dictionaries).

The article in the post you linked seems to be wanting to use "racism" where he means "institutional racism".

I also saw your other comment where you suggested "discrimination" is the word another poster meant when they said "racism". That doesn't work because according to the article you linked, discrimination requires action. Someone just offering race based theories of superiority and inferiority or raced based theories of behavior is not discriminating if they are not putting those theories into practice to do things like make hiring decisions.

In the context of codes of conduct, individual racism is what's relevant.

Here's a good example of a black person writing racist material, according to most definitions:

That in the evolution of the species, in what some
people call the Ontogenetic evolution of humankind,
that in the evolution of the species the human
family separated in a sense that one branch of the
family stopped its evolutionary path and simply
depended upon the central nervous system as the
total machinery for understanding reality. Whereas,
the root of the family continued its path and not
only evolved a central nervous system but developed
what I called at that time an essential melanic
system. And that I even went so far as to try to
develop a little formula and suggested that CNS +
EMS = HB. CNS (Central Nervous System) + EMS
(Essential Melanic System) = HB (Human Being). That
the central nervous system combined with the
essential melanic system is what makes you human.
That, in fact, to be human is to be Black.

That's from Dr. Wade Nobles, Professor Emeritus of African American studies at San Francisco State University, in his book "Seeking the Sakhu: Foundational Writings for an African Psychology". He was a leader in the melanin movement, a group of people who believe a pseudoscientific thing often called "Melanin Theory" that attributes various amazing, sometimes magical, properties to melanin. It's big in Black Supremacist circles. Here's a good look at it from the Skeptical Inquirer [1].

Some of the awesomeness of melanin can be seen in this quote from Carol Barnes' "Melanin: The Chemical Key to Black Greatness":

Melanin is responsible for the existence of
civilization, philosophy, religion, truth, justice,
and righteousness. Individuals (whites) containing
low levels of Melanin will behave in a barbaric
manner. Melanin gives humans the ability to FEEL
because it is the absorber of all frequencies of
energy. Since whites have the least amount of
Melanin, this is why they are perceived by People of
Color as generally being rigid, unfeeling
(heartless), cold, calculating, mental, and
"unspiritual."
