The one that apparently is the argument so complete there's no way to refute it is-
Obviously it's about rape. At a stretch maybe serious sexual assault.
Any other reasons or crimes given why women and girls need single sex spaces is trivial/irrelevant so should be simply ignored.
If a girl or woman is raped by a male in a single sex space (it's always just toilets mentioned).
Then it will by definition be a cis man who did it. Males with trans identities by definition would never do anything like that. ( Fact that any old male can saunter in never addressed).
If a cis man wants to rape a woman or girl then he will. Nothing anyone can do about that. Just fact of life.
The idea that a sign on a door will stop rapists is laughable. Prepared to rape but obey toilet sign? FFS that's so stupid. Who would ever think that! Are they thick or what?
I have seen a thread on OJ twit with all the comments more or less LAUGHING!
Hilarious comments man I'm going to follow her and rape her, oh no a sign! Thwarted.
What does this last one tell you. Well everything anyone needs to know to understand the attitude of a group (seems a fairly large group) of the gender > sex people who comment on this topic on Twitter.
No Twitter isn't real life at all.
But to see a stack of people taking the time to LAUGH at rape. That's not great to see written on a public forum.
Oh and last argument.
If anything happens report it. Can't see any problem at all. Just report. Easy.
