Check out twitter for #selbstbestimmungsgesetz, which is the name of the proposed legislation. It is being pushed by Greens and liberals (FDP). There is some resistance and a German version of the LGB Alliance exists.
You’re right, the discourse is where Britain was in about 2017. Recently, a successful ‘mummy blogger’, Nora Imlau, tweeted that it was never OK to say TWANW. It’s the sort of safe right-on and ‘inclusive’ thing that prissy middle-class Lady Bountiful influencers like to be seen supporting. Mainstream women’s magazines also make vague references to ‘gender diversity’ but never spell out that this actually means recognising fully intact males as female.
The other thing that is striking about Germany is the extent to which so-called intersex conditions have been put in the same category as trans. There is a law that allows a third sex marker for people with such conditions, but anecdotally it is also being used by trans-identified people to alter their documents.
The Greens are the party most supportive of gender identity ideology. Interestingly, they have only recently emerged from a serious historical pedophilia scandal. In the 1980s, the Green Party was a political home for several pro-pedophilia activists. Their demands were marketed as ‘sexual self-determination’ for children and adolescents. It must be said that the party tried quite hard to investigate and that it issued an apology. But a proposed law that allows 14-year olds to change their legal sex without any meaningful gate-keeping seems oddly myopic given the circumstances.
A high-ranking functionary in ILGA, a European lobbying group at the forefront of pushing for gender self-ID, is also German, I believe.
