On the flip side, forcing someone to believe in gender identity is also unacceptable. As is creating a hostile working environment for them, so no calling them terfs/bigots etc
This is where it’s going to get really tricky. I don’t want to be forced to believe in gender identity, nor to act as if I do.
If I know a person is biologically male, it goes against my sincere and deeply held beliefs to refer to that person as if they were female. Forcing me to do so would be compelled speech and I would experience it as harassment.
But if I refer to that person with male pronouns, that person would say I was harassing them.
The Christian bakers were allowed to refuse to write a pro gay marriage slogan on a cake. Can I similarly be allowed to refuse to refer to a biologically male person with female pronouns? And if so, how would I then refer to that person, supposing I were to work with them, in a way they didn’t feel constituted harassment, and I didn’t feel constituted coercion?
It’s a dilemma. Now that my beliefs are recognised as being protected in law, it’s one which will have to be resolved at some point.
