If anyone has been in court as a witness especially for a traumatic case like being raped, they will know that it is an extremely stressful situation.
The defence can be quite vicious in their questioning (there is a court case being brought in Scotland because a rape victim felt so badly bullied while giving evidence) and will jump on hesitations or stumbles if it helps them undermine the woman’s evidence.
How unbelievably stressful must it be to have to remember, in each sentence where you are forced to relive your traumatic experience at the hands of a male , to have to remember to refer to them as anything other than ‘he’.
The rape victim experienced the actions of a male, his identity didn’t rape her, he used his male body.
Even if the court allows the victim to describe what happened as she experienced it, hearing her attacker referred to as female will be discombobulating and has the side issue of potentially being confusing to the jury.
Confusing the jury in a rape trial is not going to be to the benefit of the victim. Considering that police only manage to bring a charge in 1% of reported rapes, I would suggest this further contributes to the effective decriminalisation of rape in this country.
