I don't think we need to make those arguments. People in general know TIMs are not women when they see it.
Recently I have been wondering why there isn't a backlash, why everyone except MN is going along with the TRA rhetoric. I have a wide range of friends, peers and colleagues. They know I am a "safe space", I won't hate on your beliefs, I will always want to understand. So I have been testing the waters to see where people stand and why.
The results? They have no fucking clue whatsoever about trans anything.
I ask what they think about the weightlifting, kickboxing, cycling, basketball wins by TIMs. I ask what they think of Labour's new women's officer (without saying anything about the women's officer being a TIM).
With sports they think I've been at the alternative news, of the Freddie Starr ate my hamster variety. I have been laughed at for believing such obviously fake news. I show reliable reporting and photos of the sportspeople and the overwhelming reaction is disbelief because something so obviously wrong can't be happening. They kind of disengage because it is so implausible. Men are far more outraged about the sporting "unfairness" than women according to my anecdata.
As for the Labour Party, well, Harriet Harman's women's officer isn't she? A bit loony sometimes but mostly sensible. What, she's not? Lily who?
Nobody outside terf and tra echochambers seems to have a clue that Lily exists, never mind being women's officer for the labour party. On reflection, why would they? She isn't in the mainstream media. I haven't heard her once this month on a news programme talking about the impact of brexit on women, the impact of the shortage of GPs and midwives (who are often women and are used by women), the impact on women of Syria, the Weinstein stuff, girl's attainment in exams compared to the world, state run childcare options, the England women's football team new manager. Nothing. She is nowhere.
She isn't doing the job of women's officer and so nobody outside the echo chambers has a clue she exists, never mind what she believes.
I would get a lot more sports stories in the press, which is always hard but maybe a photo of a TIM next to a standard female athlete will appeal to the papers.
I think we should demand that Lily does her bloody job! Ignore trans and ask her opinions on everyday politics that people care about. Her total lack of competence will soon come out, people will see that the emperor has no clothes.
