At the risk of boring even myself, what proportion of the US population do you think is trans-identifying and what is your source for that? That is, after all, the sole number I got from the Williams Institute and I'm happy to accept it's wrong if it is indeed wrong. (Weirdly, despite several people falling over themselves to tell me it's biased nonsense, and despite me asking several times now, no-one has so far managed to tell me what source I should be using instead.)
I'll now jog over from the "school shootings perpetrated by all trans-identifying men" to "mass shootings perpetrated by trans-identifying women" pitch. A couple of questions if I may - how many mass shootings, and over which time frame, have you counted as having been perpetrated by women? And what are you counting as a "mass-shooting", because as anyone with the slightest knowledge of gun control arguments is aware that is a VERY contentious point.
