You are right to be chilled and who it's going to rebound on is women, kids and genuine transsexuals who wouldn't hurt a fly.
Queer Theory is very wrapped up with paedophilia, discussions of it being a 'sexual orientation' etc and heavily wrapped up in the liberal, sex positive discussion of 'child sex work' (again, this whole liberal view of prostitution and the rape and exploitation of women on film as 'work' has chilling implications). Google Janet Mock. She thinks child prostitution is liberating and empowering.
I've seen transactivists who openly declare themselves 'men rights activists and anti feminists' dog piling feminists in their support of the transing of children. I've seen mothers of trans kids talking about 'support of the trans community' from these people, mothers taking advice from these people.
My peak moment was Bruce Jenner - he's pro trump, anti gay marriage, anti abortion, has a $1m boob job, kept his dick, still has PIV sex, and likes dressing up in ladies undies (I bet he has hours of fun all by himself) and somehow me being a little bit suspicious and refusing to call him brave, or to agree he deserved to take a place from a woman as 'Woman of the Year' makes me transphobic.
Another was Frank Maloney, now Kelly, by his own admission a wife beater who nearly strangled his wife to death due to the stress of his 'gender confusion' - he's now on the NHS website as a trans casestudy. That flies in the face of all we know, all the data, on domestic violence and why men beat up women. Even better, if he did it now, that crime would be recorded as committed by a woman.
These dudes NEED kids as part of their fantasy - they have erotisized being a woman, and as part of their 'we are the most oppressed women every to walk the earth' narrative they need that story that things would have been so much simpler if they could have transed as a child.
