Female Pseudonym of President Donald Trump: Persons with multiple personality often have both male and female alternate personalities

Since the last time I checked the Wikipedia entry, “Pseudonyms of Donald Trump” (1), it has added a female pseudonym, "Carolin Gallego,” which he used in a 1992 letter to New York Magazine:

“Based on the fact that I work for Donald Trump as his secretary — and therefore know him well — I think he treats women with great respect, contrary to what Julie Baumgold implied in her article … I do not believe any man in America gets more calls from women wanting to see him, meet him, or go out with him. The most beautiful women, the most successful women — all women love Donald Trump.—Carolin Gallego, December 7, 1992” (2).

I do not have the information I would need to diagnose multiple personality, but his use of pseudonyms raises the issue.

Added later July 17: Trump's hair is not naturally blond. Who chooses to do that? Carolin?
