a transwoman calls her out on transphobia at a signing of her book full of unsubstantiated allegations against men and (what a surprise) the transwoman is treated to a truculent tirade of verbal abuse,

means not being ashamed to be seen as trans. What choice would I have in that? ... but I'm not going to put my life on the line standing up for loud mouth bullies who demand to flaunt their BDSM in public.
