He's posted on Twitter: 'i am overtly + unapologetically cisphobic. cis people, on the whole, are just awful + there needs to be a massive state-sponsored programme of re-education'.
Cisphobia = hating and discriminating against anyone who is 'cis'.
Cis = someone who conforms to gender stereotypes associated with their biological sex (although Harrop has said that he defines 'cis' as anyone who isn't trans - which means there is a licensed doctor saying he hates the majority of his patients and proudly discriminates against them).
