"What do you plan to do with all the female people excluded from services, resources, facilities, health care and such?"
(You will have to explain that yes Virginia, they really do exist.)
And then the inevitable follow up questions:
"So do you believe it's ok to exclude if only a small number of people are affected? Surely then it's ok to exclude male people from female facilities rather than a much bigger percentage of female people be excluded?"
"Does inclusion only matter for male people?"
"How many protected characteristics are there?"
"Where does it say that TQ+ interests trump all other protected characteristics? Or are you just against people of minority faith, culture, belief, disability, homosexuality? And isn't that a bit.... bigoted?"
"Have you heard of the word 'intersectionality at all and do you know what it means?"
"Do you believe in religious tolerance? Or only tolerance for people like you who hold your beliefs? Are your beliefs morally superior to others making you better qualified to govern others? Do you believe people not like you, with views you don't agree with, should be a subclass deprived of equality of resources and facilities granted to people who are like you? How does this not just make you a raging snob? What is the difference between this view and colonialism based on perception of moral and cultural superiority granting the right to suppress and harm others and remove their inferior way of life?"
"Do you think people in this subclass and females in general should be paying the same tax in your ideal world where they get less than those born male?"
"How exactly are you managing this extreme end sex based thinking while at the same time arguing that the reason for ending sex based rights is that sex isn't a thing?"
Mind you, they'll have long since run away by this point.
