I noticed that a key part of their movement is language. Transexuals and transvestites have been around for years but I don't ever remember anyone, including themselves, insisting that they literally were women.
These are the exact same men, except now everyone is insisting that they literally are women.
They have basically rebranded themselves, cleverly, with language being a key part of this, because I can't imagine anyone shouting on twitter or on pride marches 'transvestites are women and anyone who disagrees is a hateful vestphobic bigot!'
It seems they knew nobody would be fooled by that so they changed both transsexual and transvestite into 'transwoman' to gain sympathy and then use that sympathy to drive their ideology forward.
