I'm still working my way through all the documents, but the draft guidance states:
The Welsh Government is fully committed to the United Nations Convention on the Rights of the Child (UNCRC).
Protective and preventative RSE is informed by many of the protective articles embedded in the UNCRC. ... Article 8 [covers] the right to an identity (including gender and sexual identity)
I thought this looked a bit odd, so I looked up Article 8. This is what it actually says:
Article 8
1. States Parties undertake to respect the right of the child to preserve his or her identity, including nationality, name and family relations as recognized by law without unlawful interference.
2. Where a child is illegally deprived of some or all of the elements of his or her identity, States Parties shall provide appropriate assistance and protection, with a view to re-establishing speedily his or her identity.
That's it. Absolutely nothing about 'gender and sexual identity'. You'd think the people writing a government consultation could find 30 seconds to find out what an international convention actually said, instead of making it up, or getting a garbled version from Stonewall or somewhere.
