Let me ask you this- imagine she was your grandmother. Or mother.
We have an (apparently) unwitnessed exchange between two people and you conclude based on…your extensive knowledge of Dame Hussey…that you you can drop the C bomb.
I know my grandmothers, my mother, and their strengths and weaknesses. I have an idea of what they would have said, where and when. I know the discrimination faced by my non-English speaking grandmother throughout her life. The "speak white" comments. The folks who deliberately took advantage of her & my grandfather because of their lack of English language skills.
And I know the recurrent "oh, it doesn't mean anything" racism in Canada that we repeatedly deny, ignore, or say "well, at least we're not as bad as the Americans". My childhood neighbour observed "Canadians are at least as racist as Americans, they just do it at an individual, not so much at the national level".
The recurrent exclusion of people as "the other"; the recurrent "no, where are you really from" and all the other shit that is accepted (but is inherent national racism that we deny because we didn't fight a civil war to keep our slaves)... fuck that.
Look at Sarah Hussey, then look at the war hero, the Duke Of Sussex, who fled the UK with his biracial wife in no small part because of EDIT TO MEET SITE GUIDELINES like Sarah.
Who would you rather have a beer with? Sarah or Harry?
