Believe it or not, it can be implied with your original comment. You’re saying “of course it’s a white male cisgender CEO” - but if it were, for example, a black trans person, would you suddenly go “of course it’s a black trans CEO”? By labelling something, you’re suddenly saying that everything that you didn’t explicitly label is somehow different - somehow, a non-white, non-male, non-cis CEO is different than a white male cis CEO.

As another user said, it’s an unnecessary label for the context at hand that serves, at best, to make people go “ok, the labels are unnecessary but go for it”, and at worst it divides people because people are stupid and will get hung up on culture and identity in contexts where neither are needed.

EDIT: Should clarify, I understand you were stereotyping the old rich white man, but adding the “cisgender” bit was unnecessary for that purpose. Most people will get that regardless and it’s ultimately a semantics thing, but it can be dangerous rhetoric if you throw it around willy-nilly. Like I said - everything you didn’t explicitly label is somehow different, even if you just said “old rich white guy”.
