Here are a few questions you could ask. I'd certainly love to see an answer to even just one of them:
If a female survivor asks for a female-only therapeutic environment, is this available at your centre?
Does she have to specifically ask for a female-only therapeutic environment or is this offered as standard?
Do you acknowledge that perception is subjective and that unlike you, a female survivor may perceive males as male regardless of their identity?
Do you accept that involuntary trauma responses to males, of any identity, are not rooted in the survivor's prejudice against males who identify as trans, but in her experience of male violence?
Given that female survivors typically only approach your service when they are in crisis and vulnerable, do you understand that they may feel unable to raise concerns with you about the presence of males in what they expect (and you advertise) to be a female-only therapeutic environment?
The Rape Crisis National Service Standards state that
Underpinning the approach of all specialist Rape Crisis Centres is an evidence-based understanding of how experiences of sexual violence and sexual abuse can impact individual survivors. Rape Crisis Centres provide a trauma informed approach to practice and delivery that is both appropriate to and effective when supporting survivors of all forms of sexual violence.
Can you explain how your centre can meet this high standard of service delivery in a mixed-sex therapeutic environment, given the strength of the evidence on the needs of female survivors to recover in a female-only therapeutic environment?
Can you explain how a mixed-sex therapeutic environment is appropriate and effective in delivering your service to female survivors of male sexual violence, especially given that most if not all female survivors can only recover in a female-only therapeutic environment?
Are you aware that your stated refusal to cater to female survivors who identify as trans is unlawful discrimination on the basis of sex if these females remain legally female (that is if they are not in possession of a Gender Recognition Certificate?)
Are you aware that if you are catering to male survivors who identify as trans who remain legally male while refusing to cater to all other legal males, you are also unlawfully discriminating against the latter group?
A service can only legally exclude males if it applies a sex-based exemption, which applies differently to males who identify as trans with a GRC and those without a GRC.
How are you ensuring that you deliver a lawful service given your stated ideological position on including all males who identify as trans, regardless of their legal sex, and excluding all females who identify as trans, regardless of their legal sex?
Are you seeking feedback from your service users on providing a mixed-sex therapeutic environment? And if you do so, are you seeking this feedback in a way that allows female survivors to raise any concerns they may have without fear of reprisals or loss of access to your service?
What processes do you have in place to deal with a female survivor who raises concerns with you directly? Do these processes align with the National Service Standards?
