I think you know that because a viable alternative hasn't yet been found, it doesn't mean the one proposed is the only possible answer.
That's the same argument biblical literalists use as their 'gotcha' argument. Because you can't explain where the universe comes from, then their explanation must be true. The flaw in logic is obvious.
The problems with Blanchard are numerous and cannot be handwaved away by saying that any trans women who doesn't fit into the two categories (most of them) must be lying.
Seriously watch Contrapoints entire video on this, she goes into considerable detail about her motivations for transition etc. Yes she might be lying, but to say that every trans person in the world who isn't a 'homosexual-transexual' is a liar, really?
And what kind of Orwellian world do you live in where denial of something is just further evidence of guilt?!
