I have just seen the BG new guidelines on inclusion (here.
They go against all of their own safeguarding policies by saying that children should use the changing room of the gender in which they identify (so boys who identify as girls can use the girls changing room. Their own safeguarding guidelines state changing rooms should be single sex.
They then say if the girls don't like it they can go elsewhere. If an individual remains unhappy about a trans person using facilities appropriate to their gender identity, then they should make alternative arrangements
They also say the same for residential trips. And because privacy is of greatest important (although not for girls it would seem), a teenage girl (or her parents) may not be told she is sharing a room with a teenage boy (who identifies as a girl.)
This goes against all of their published safeguarding guidelines which says there should be single sex changing rooms, washing facilities and sleeping arrangements (for trips).
They also say children under 16 can compete in the gender they identify with. So boys can compete against the girls if they wish.
(Girls can also complete against boys but its highly unlikely they will).
Their guidelines on gender also, say Signs can appear at a very young age e.g. a child refusing to wear typical clothes of their gender or taking part in non- typical games. I'd better tell my short haired, trouser wearing, rugby playing niece that the leading governing body for one of the most popular sports for children believe she is actually a boy.
AIBU in thinking this is sexist and dangerous and BG should be held to account?
