What gives?

I watched part of a recent video by Ray Williams who went from transgender philosopher Rachel to detransitioning and warning people about the evils of the "transgender ideology". These 180 degree about faces make me very skeptical about the original motives for some people's transitions but I am even more perturbed regarding why someone would do what he is doing.

If there are happily transitioned people elsewhere, their lives are not exactly his concern and he should simply be happy for them and for himself for finding his way.
