Yep, in the context of a hate crime. Not standalone. Seems reasonable.

I don't think you read the link you posted. To quote from it

" Speaking for the [Canadian Bar Association], the President, [...] made explicit the protections for transgender people which were already contained in the prohibition on discrimination based on sexual orientation; and did not pose any risk to freedom of expression"

So it's about discrimination, and freedom of expression is not affected. Further

"Peterson argued that the law would classify the failure to use preferred pronouns of transgender people as hate speech. According to legal experts, including law professors Brenda Cossman of the University of Toronto and Kyle Kirkup of the University of Ottawa, not using preferred pronouns would not meet legal standards for hate speech"

So getting him/her wrong is not hate speech, so... problem?

What I'm getting from you is anger+fear, and what I'm not getting is why treating TGs decently bother you so much.
