For being their biggest talking point as to why we need to blindly play along with their mental illness manifestation, you'd think they'd be able to cite a source other than WPATH, Mermaids, or some other troon charity whose financial solvency depends on trooning out little boys and girls who play with the "wrong toy".
Suicide threats are what's known as "Emotional blackmail"- do you know who else uses suicide threats to subdue others into going along with what they want? That's right- abusive people.
