And if the OP is bedazzled by a long thread and therefore confused about what questions have been asked.
I've done some pre-reading work for you, and distilled the thread to make it easier. So, the key questions arising in the discussion you mentioned you were keen to engage with are:
How do you know you're a woman?
So you think that NO transperson anywhere ever is a peodophile?
And HotRocker's great list:
You’re unhappy with DBS checks because they only flag up retrospective offending, so you‘d like suggestions for a more watertight system.
You believe that violent and sexual offenders should be kept out of the female estate.
You evidently believe that not all people who claim to be trans are in fact trans, therefor by extension, if you continue that logic, that some people may seek to abuse a system of self ID for nefarious purposes.
So what are your suggestions? Nobody can identify an abuser before they’ve been caught, so how do we identify abusive men who wish to self ID as a woman for the purposes of predating on women and children?
How can we ensure that any male bodied individual who gains access to female single sex spaces will not commit any offences?
How can we correctly identify people who are genuinely trans, as opposed to people like Karen White, who’s trans identity you question?
You clearly believe that a system of safeguarding should be implemented to prevent abusive predatory men gaining access to women and children, so how do you think that should work?
