I'm reading Matilda to DS2 at the moment. Transphobic? 
So... because The Trunchbull displays characteristics which are traditionally considered more 'masculine', she must therefore be Trans? WTF!
Surely that is just reinforcing the old gender stereotypes and is therefore extremely misogynistic and possibly homophobic (are all butch women now actually trans? Jesus)?
The irony of protesting long and loud about how gender is all in the mind, it's a spectrum, it's fine to not confirm, etc etc - and then imposing the view that obviously anyone nonconforming MUST therefore be the opposite gender to their physical body! Seems to me that many TRAs are the most rigid thinking, repressed homophobes of all.
