It wasn’t an angry rant. The argument is that preferred pronouns will, obviously, be part of an individual’s “gender identity and expression”. Refusal to use them won’t be enough to be considered hate speech, but it will be discrimination. This could lead to some other punishments including fines. Refusal to pay fines as a matter of principle will eventually result in imprisonment.
In order for imprisonment not to be a possible outcome preferred pronouns would need to be explicitly excluded from “gender identity and expression”. Would you agree with this?
