I think the comment meant to point out that these humorous take on a tragedy are only accepted as part of a russiophobic perspective. I tend to agree, although I don’t find it offensive I understand that similar comments on for example, the killing of a ukranian ballet dancer, would be seen differently by all of us. Hence, the xenophobia. Ukranian is western and we relate.

Just changing the victim nationality makes it palatable for jokes, that’s something that calls for observation
Dissociation, of course.
