It's more that the author of that article is using irrational prejudice to attract attention to themself and get some work from it.
Couple of random points - the author says that women are a race. The author also repeats the silly propaganda about "rule of thumb" which makes no sense at all, despite knowing that the false etymology explicitly requires the existence of time travel by placing the "origin" of the phrase to centuries
after it was used in extant writing (and, of course, it's probably older than that - that's just the oldest surviving written use of it). Then there's the idea that 'itis', an extremely common ending for a medical problem (it means "swollen, inflamed") is racist when used to refer to an unspecified disease. Etc, etc.
The simplest solution is to do what people promoting this sort of thing want - target the biological group identity they consider to be the most inferior. Change every phrase to "cisgender straight white men are ****" and all the complaints would stop, at least until they could figure out a way they could make it worse.
