It makes me very uncomfortable to make speech and holding opinions (whether factual or not) illegal.
It sets a dangerous precedent and is a double edged sword. What if we’d declared criticizing internment camps or the 60’s scoop as hateful prejudice against Canada? What if the next government makes speaking against oil illegal?
Education and acknowledgement is the answer. We need to continue making everything about residential schools public. It should be easy to see evidence of their practices, know who ran them, how many children died and where they’re buried, etc. It should be obvious this happened and was awful.
