The key point here is that Dr. V was outed as a liar and a fraud. The transgender issue is an intriguing but irrelevant twist.
From the linked article: “The town’s lawyers also suspected that at one point she might have been known by a different name, and they asked her to reveal it. When she refused, the judge asked her to sign an affidavit saying she had always gone by Essay Anne Vanderbilt. She refused that request, too…” Naturally any reporter doing a story on this person is going to investigate that angle, to see if there was indeed a name change as suggested. And having found that to be the case, is going to include that information in the story.
The gender change is insignificant. Had it been Mary Krol who became Essay Anne Vanderbilt, or Stephen Krol who became Arthur James Vanderbilt, it would have been reported just like the transformation from Stephen Krol to Essay Anne Vanderbilt was. Unless one believes there is something inherently awful in being transgendered, there is no reason to hide the fact. The biggest fuss is being made by people like Gerri Jordan, with the "lesbian auto mechanic” comment, and those who think that just because one is transgender then one should be shielded from having all their lies fully exposed. The people getting their panties in a twist seem to be those who are inordinately focused on gender identity when that’s just an incidental detail. I see no sign that the author or any of the folks interviewed make a big deal out of it.
