Thank you for sharing the SM reactions. It's sad but unsurprising now that Mermaids and Stonewall are disappointed that child protection is prioritised over ideology, and that adult SM figures with TQ+ identities are immediately signposting how to escape the law and child protection to follow the ideology.
It's all going to be useful experience for Westminster, in this and in the schools guidance and in Liz Truss's bill debate: there are no ethics. There is no capacity for reasonability or consideration of the wider picture here. As a reasonable, just and sane movement could have been expected to have listened to and understood women's voices and issues and needs, and worked with them to resolve them and find ways that worked for all, you would expect care that children have the best possible ways forward.
But no. Blind faith and sod the consequences is always the cry of the adults leading this. And law needs to present boundaries that they cannot wangle.
