The lawsuits make him seem like a hypocrite, but they don't invalidate the point: that the idea of criminalizing the refusal to use someone's preferred pronouns is ridiculous.
No, he's still a hypocrite because you literally cannot use the laws as written to do what he says that you can. If you refuse to use someone's preferred pronouns, you're not a criminal, you're just a literal piece of human trash.
However, if you are in a position of power, such as a teacher, and you refuse to use that person's pronouns after having been corrected by the student, You not just a piece of human trash, you're also being discriminatory towards a transgender person and making them unsafe, which under Ontario law and Canadian Federal law, is likely to be a crime. That's never been tested, and there's never been a court case, so we don't know full legal arguments for both sides, but I don't think that the teacher in that situation would have a leg to stand on, legally, especially considering "free speech" as it is defined in the public conscience, is not actually protected as such in Canada. You can't just say whatever you want here.
