Thank you for your question.
I'm unfamiliar with the film. I can only speak broadly and say that there always has been and always will be, in democratic societies, speech that makes people uncomfortable.
The question is, first and foremost, is it lawful? There is a very high bar in Canada for what constitutes illegal speech. If it reaches or exceeds that bar, then it shouldn't be permitted. Everything else, I think, is fair game. However, that doesn't mean that broadcasters or social media platforms have to amplify it and extend their audience for commercial reasons beyond that which it would achieve on its own merits.
