Since she began speaking about this topic publicly, Shrier's position has always been that she respects adults' right/decision to alter their bodies & to claim a "trans" identity because she believes that for some adults (such as Buck Angel) it's a legitimate, beneficial way of ameliorating their deep distress. She has also said many times that she uses the preferred pronouns of trans-identified adults.

Whether or not Shrier truly believes that there is really is such a thing as "true trans" or "justifiable adult transition" is another matter. But in today's climate, I certainly can see why Shrier and her advisers would conclude this is the most tenable and politic position for her to take.

Lots of people take positions on various topics that some other other people find contradictory when viewed from their own perspective. That doesn't mean those positions are inherently illogical or unreasonable.
