Oh dear, so Lizzie Marvelly has been offended by Family First's objection to the unisex toilet issue and wants to inject 'a dose of reality' - hers.
I am a conservative Christian myself and would agree with Family First's views.
But to say that view is 'anti-trans' or 'phobic' is far from the case.
With the utmost respect for these gender differences, toilets have been segregated for however many decades because in a society where the vast majority are male and female, there are safety concerns where adults of the opposite sex could be a danger to the other, and especially to children.
You mention in our own homes we all use the same toilet. When it comes to sharing with strangers the argument is obviously different.
