I've never seen the concerns listed in paragraph 9 (children taking hormones, people with penises accessing female only spaces etc) addressed.
As this is a predominantly female site used by mothers, I'd say these are legitimate concerns we have.
No way would I want my child started on a hormone treatment when the long term consequences are unknown.
Call me an extremist but I also wouldn't want my child to have such drastic surgeries which would render them infertile.
