This is not a relevant or symmetrical comparison.
A female person choosing to take a risk to use the male toilets is consenting to that risk for herself. It is actually just as much as an invasion of privacy and dignity to male people though when a female person enters a male single sex provision. It is certainly not respecting those male people when a female does it.
However, if you are trying to then deny that male people in general, meaning male people with a transgender identity are not a much higher risk of causing a female person harm by accessing a female single sex provision (including groups and sports), then I think you have believed misinformation.
It is also not just about physical risk to safety. There are many types of harms that female people need female single sex provisions to be safeguarded against:
Harms include:
-Rape and sexual assault.
-Violence.
-Sexual abuse that is not rape or sexual assault.
-Sexual abuse that also includes solo sexual acts or using the experience in future sexual acts.
-Any other abuse that may include verbal abuse, intimidation in any way etc, this includes inappropriate questions and comments.
-A male person's presence where female people need privacy and dignity.
-A male person's presence where female people need to feel safe from any male person's presence (over the age of about 8 years old).
-Female people self-excluding knowing that there may be a male person accessing that provision.
-Female people not having the freedom to discuss the issues that cause them distress, concern, or that they need to talk about because a male person is present.
-Female children (and female adults) learning to have no or too low personal boundaries because they have been taught that male people are female people and that they should ignore and overcome feelings of discomfort.
Narrowing the discussion to sex and violence offences does not remove these other harms from consideration for female single sex spaces.
However, discussion of why a group of male people should not be treated differently to all other male people is relevant to the discussion as to why no male people at all should be given special access to those female single sex spaces.
