How utterly mad is the idea that someone would change their gender specifically to victimize people of the gender that they have changed to (or frankly, to victimize anyone)?

About as mad as people supporting someone for making such an insane claim, I suppose.

Or as mad as making such a claim in order to profit financially from it, presuming that hurting the innocent matters less than the money they would receive, yet never be able to spend in 100 lifetimes.

Or as mad as that someone with some of the most creative ideas and most vivid imagination of their age can't begin to conceive of the reality of someone needing to be true to themselves.
