I would like to add a variable. An interpretation based on a religious text has to be put it in the context of freedom of religion. In Canada, freedom of religion is understood as requiring the demonstration of sincere belief. That's the fundamental test. It's not the legitimacy of a belief or an interpretation of a particular religious text in light of some religious tradition. It's really the sincere and subjective belief of the individual who is making the speech.
In my opinion, the issue of demographics doesn't matter when there are a multitude of possible interpretations of religious texts and the most fundamental criterion is sincerity. It can certainly give rise to what we call in our brief a “black hole”, which will allow all kinds of speech, as long as it is believed to be based on a religious text. That provides a loophole for promoting hatred, until the Parliament of Canada decides to change its position.
