Oh, important to note that exceptions to the above are malicious stereotypes or those arrived at without contact with the group being stereotyped, which do not tend to be valid assessments of average group properties.

WRT the blog, I figured that the point of them was that they contain a grain of truth when speaking about white hipsters, and for all I know possibly white hipsters in the US do sometimes go around self-consciously having black friends. But in the Canadian context there's nothing to satirize there, in the absence of the black-white divide (due to the black half being missing), so it's more baffling than irritating. But if your point is that these are things that don't apply to all white people, then I guess that still works.
