I was speaking about Toronto, where there are few natives. The point, and all the other similar ones you quoted, is correct. You may not like the truth, but that's your problem.
Yes, if you broaden to look beyond Toronto, especially in the West, then natives take over as the #1 problem. In Toronto it's blacks because we have few natives. Either way, both blacks and natives have a horrendous cultural problem that causes them to inflict violence on the rest of us. Here in Toronto despite being a tiny fraction of the population blacks are responsible for almost all the street violence.
You quoted a Star article which did point out that blacks commit an enormously disproportionate share of the violence, but that the rest of the population still committed the remainder. Well, that's a bit dodgy, because if you read that article carefully, you will see that the remainder of the violence is of a lower order than what the black community is doing, with the exception of domestic violence.
You can point out that there is a problem with domestic violence in this country, and in every country, and that's true. I agree. Pointing that out does not reduce in any way the horrible problem that the black community has become for us all. It just means that we have more than one problem to solve in this society. (Domestic violence does not appear to follow racial lines, blacks commit their share of it, as do all races. I'd hazard a guess that blacks commit more per capita, just because blacks commit more crimes per capita in general).
Now you can get upset about all these facts and start yelling "racist! racist!" but that's just stupid. "Race" is a cultural construct, not a genetic one, so whatever is going on here with blacks is something cultural. No doubt it has historic causes, and we can all get together and sing songs and feel bad for the poor oppressed black man of yesteryear. But in the modern world it's a problem, one we have to deal with, and denying that it's a problem isn't helpful. Honestly, if we can solve this problem the #1 beneficiary will be black people, who are in fact the #1 victims of all this horrendous violence.
