It is too vague. I think they’re implying calls for genocide, calls for violence, or things of that nature. Either way, that’s a problem with hate speech laws in general, not C-16.
My understanding for why it’s vague is that if it’s well defined, it becomes easier to loophole either as prosecution or defendant. The law is worded such the way it is so that a judge and Jury can determine whether or not a particular incident falls under hate speech without having to set precedent.
I get that, but I think that laws need to be as specific as possible.
