It is a bit provocative of her to have such a character when she has already received so much hate on twitter etc about her views and her lengthy essay on the subject
Her essay was about the reality of male violence and the needs of female victims of male violence to receive help in recovering from their trauma in a female-only therapeutic environment.
It was not about crossdressing. It was not about the trans community and it certainly wasn't about JK Rowling denying trans people exist or expressing the least negative feelings about them.
It was about female erasure as a result of an extreme ideology pushed by a small number of activists and how certain policies they advocate for are harmful to women.
Her essay was about the needs, the rights and the feelings of female people in the UK right now. That's it.
And it isn't provocative to include a sentence about a suspect dressing up in a wig and a women's coat in order to disguise himself. We keep being told that being trans is about much more than wearing feminine-coded clothing and that doing so is never a disguise for nefarious purposes. Then there's no problem here.
P.S. I am somewhat bemused by all the handwaving about how crossdressers aren't really trans on this thread, how they can be but don't have to be etc.
Here is the Stonewall definition:
TRANS
An umbrella term to describe people whose gender is not the same as, or does not sit comfortably with, the sex they were assigned at birth.
Trans people may describe themselves using one or more of a wide variety of terms, including (but not limited to) transgender, transsexual, gender-queer (GQ), gender-fluid, non-binary, gender-variant, crossdresser, genderless, agender, nongender, third gender, bi-gender, trans man, trans woman,trans masculine, trans feminine and neutrois.
There is no qualification here. Stonewall counts crossdressers as trans precisely because they do not conform to the sex stereotypes and sex role stereotypes associated with one's sex. That defines all crossdressers as trans, regardless of whether the individual in question claims a trans identity or not.
And that crossdressers are most definitely considered to be trans by trans rights organisations is evident from the countless policies we have discussed here and elsewhere that always include the rights of crossdressers to access opposite sex facilities. Including a great many that explicitly grant this right even to those who crossdress for erotic pleasure.
