I know a couple like this.
They are very happy, they are both lovely people, they have a child who is very happy.
I am GC, I have serious objections to the behaviour and demands of TRAs and what is happening to sex-based rights.
But in terms of individual relationships and families, people should be able to live how they like without prejudice and discrimination.
I do not agree with much of what is written in that article, and it seriously underestimates the impact of the difference between people defining themselves via gender and those who maintain the right to define by sex. It isn't 'just language'.
But if a person with a penis chooses to identify gender-wise as feminine (I have heard a trans person that I respect greatly define themselves as feminine identified trans) , and have a relationship with a woman (of any sexuality - it is up to her, her relationships are a personal choice) then they should not be subject to derision.
It's a fine line here.
