Well leaving aside what I think of as a quasi-religious issue (you believe transwomen are wonen, I do not), let's focus on entirely practical issues.
How do we ensure that male bodied sex offenders, regardless of how they "identity", are kept out of women's prisons? How do we word legislation?
How do we ensure that a group of like-minded women can get together to set up a rape crisis centre free from male-bodied individuals (both as service users and service providers) free from the threat of being sued into bankruptcy (as has happened in Canada)?
How do we ensure a women's rugby league can be formed without women having to be tackled/scrum down against male-bodied individuals (thread recently in AIBU where several women players talked with first hand experience of how much higher the risk of injury was playing against male-bodied individuals)?
How do we ensure women can ask for a female-bodied HCP to carry out intimate exams without the risk of being struck off her GP's list for showing "prejudice" towards trans HCPs' protected characteristics?
How do we make provision in old fashioned swimming pools with communal, open plan, single sex changing rooms (there are at least three of these near where I live) for women who don't want to get naked in front of male bodied individuals?
It is quite clear to anyone following these debates that there's a core of transactivists for whom the answer to all these questions appears to be "you shouldn't be able to request these things". And these high-profile transactivists seem to have the ear of people in power.
You can't prevent these questions being asked by simply trying to shout #nodebate.
