The caution before moving forward with reform is welcome. However, the problem remains that the proposals are fundamentally unworkable if they rely on the presumption that it is possible to both fully allow people to live as an acquired gender (what does this mean in practice which does not resort to stereotypes?) and protect same sex spaces. The only way to do this is to accept that living as an acquired gender is circumscribed and does not allow one to be treated as the opposite sex.
Hence, one would be legally allowed to dress, call yourself and be pronouned in a manner conventionally associated with the opposite sex but one does not acquire all the protections of that sex (same sex spaces etc), but a separate set of protections for transgender people.
In other words, recognise that transgender is a category in its own right deserving of its own protections. Presumably no women’s groups would have an issue with this, but transgender groups would as they tend to equate gender with sex, and this relies on the concept of a legal sex.
The most important point recognised in the debate in Scotland is that gender does not equate with sex, and that there are risks to women and girls from the proposed law. It remains to be seen how seriously these risks are taken.
