A trans person, talks about it and come out.

It's very sad that children are bullied for perceived differences. I don't think the article makes any substantive arguments against the govt guidance though. It does raise the issue of toilets but doesn't show any acknowledgement of why single sex toilets and changing rooms are seen as important.
As for 'needing permission to experiment with what you are called or clothing', that's not what the guidelines do.
Unfortunately, Brianna won't be able to speak up about it either.

The murder of Brianna Ghey is an utterly tagic case which seems to have nothing to do with them being trans. There may be no lessons that can be learned from it but we should be wondering why two 15 year old kids were so severely disturbed as to see murder as essentially a game.
Using it as some 'argument' against a set of guidelines that weren't in place seems to me utterly disrespectful.
