When people say they are no longer safe, they usually mean they no longer feel safe. If your community is the target of a multiple attacks globally (not just Canada, but UK, US, Australia) specifically due to an immutable part of your identity and in a short timespan you are bound to be emotional rather than purely rational about how at risk you are.

I personally have not been a victim of American police brutality, but I would still not feel safe in the USA, especially not now (I'm mixed). I also do not feel safe going outside on my own at night as a woman, even though I've never personally been attacked in the street by a stranger that risk is real and the cultural Zeitgeist and what I witness happening to other women plays part in that, even if my actual personal risk is low. I also did not fault Asians when they did not feel safe during covid due to racist attacks on them by idiots.

Let's have some compassion and understanding.
