Thing is, as parents we can all celebrate decisions we've made that are rooted in our culture and our prejudices about what's right for our children, and celebrate those decisions, and those decisions can be absolutely wrong ones.
Some people believe that FGM is a positive practice which helps girls by promoting things like cleaniness, fertility, attractiveness, honour and all the rest of it. This view of FGM is a positive practice is clearly bullshit, and a parent who was featured in a tabloid talking about how they were planning to do what they saw as this positive, celebratory thing for their daughter would be arrested, and their daughter would be protected from the terrible harm that FGM would cause them.
I really, really struggle to see how this case in this thread is any different. This parent has taken a celebratory view of transition, despite the actual dangers posed to her child, and I don't know why her plan to medically damage her physically healthy child is not being investigated by the authorities rather than lauded in public.
