Sorry for al, the questions, I just don't know anyone who has this views in RL to ask about them!
It's fine - I appreciate the opportunity to discuss it as it clarifies my own thinking and counteracts her condemnation of me!
Does she accept with the feelz argument that it opens women (and genuine TW) up to risk if any man can say "I identify as a woman" and get access?
Yes, she does - but she disagrees that all men (and transwomen) should be penalised due to the possible actions of a minority.
Does she accept that women are at risk of violence from men and the majority of violent crime is committed by men? Have you discussed with her that even fully transitioned TW retain a male pattern of criminality including violent crime? If so, does she see any problem with that?
Again, yes, she accepts it - but doesn't believe that risk management should include the exclusion of innocent individuals. Men who commit crime are punished, and that is how it should be. Not protecting women from the potential risk of hypothetical offenders.
Does she recognise any differences between TW and women?
Sort of, but believes that TW have a right to be referred to as Women if they wish to be, and that the term "cis" is an acceptable prefix to distinguish between women and transwomen if necessary.
