You might wish that they had that burden... but they don't. You know why they don't have that burden? Because their first step was to redefine what constitutes a "woman" in the first place, and to make it based on an unverifiable subjective feeling. Once you've managed to stake your negotiation from the starting point of "Anyone who says they're a woman *is* a woman", then there is no argument to be made that some "women" increase the risk of other "woman", because they're all "women" and we don't exclude any "women" from the "women's prison" for that reason.Activists advocating for moving transwomen convicts into women's prisons carry the evidential burden to show that those people will not substantively impact the population being housed, for example, by making the estate significantly more (sexually) violent.
This is why that primary discussion of 1) biological reality versus subjective feelings and 2) what constitutes "real transgender" is an absolutely vital part of the debate that can't just be handwaved away or swept aside.
