Kitty Klaws, the point is that there is literally no way to tell if Ibi-Pippi is "true" trans or not. There is no gatekeeping. You can't really question the fact that she is legally declared a woman if she has the paperwork. Self ID requires absolutely no supporting evidence, which means we have to just take people at their word. So it doesn't matter to me if she is "actually trans" or an "artist." The point is self-ID can be used by anyone for any reason. Ibi-Pippi might be able to sue in some situations at not being allowed into female spaces (not sure about Danish law), and I also suspect that legally you could get into trouble if you allow some trans people into your single sex space but not others.
Hypothetical example: let's pretend you let someone who looks like Laverne Cox into the women's changing room, but not someone who looks like Ibi-Pippi. In this completely made-up scenario, they're both trans women, both have self-declared female IDs, neither has had gender reassignment surgery. In any case that last part isn't relevant because you haven't set clear sex/gender reassignment criteria for the changing room and besides you aren't going to check the genitals of all your guests before they walk in.. Would you not in theory be discriminating against a subset of trans women if you don't allow someone who looks like Ibi-Pippi in, but you do allow more "passing" trans women in? The same principle would probably hold for other same-sex activities and spaces.
Daim: if a male legally declares herself a woman, enters your female changing room, exposes her penis to you but is just standing still staring at you, what are you going to object to? Are you going to complain that you were made to feel uncomfortable by this self-declared woman, who has documents to back up her perceived right to be there? Like Pratchet said, how do you even name the crime/problem, and what recourse do you have to fix it? There's also a stigma attached to speaking up for fear of being labelled transphobic.
I would like to know from our trans activist friends, actually, what the stats are for rates of violence against trans people in Ireland (or other countries) pre- and post-self-ID. I'd also be very interested to know how self-ID has affected other important data such as suicide rates. I haven't come across such numbers before. Anything that focuses on changes in violence rates in single-sex spaces against trans people would be especially appreciated. How have these numbers been affected? What's the evidence look like of objective harm reduction to trans people with a self-ID policy? Genuinely curious, so thanks very much in advance.
