When you look at Boris Johnson's comments there's nothing to deconstruct. There's no guile, there's no pretense, there's just ridicule and malice. It is the type of jibe a person on the right says because they think nobody will be concerned about it. One almost expects bigotry from many on the right, though it doesn't make it less reprehensible.
It is more surprising to see on the left, but also dangerous because the left must be a bulwark against the normalization of hatred and irrationality. To see people on the left rightly call out Israeli "what-aboutery" and then engage in what-aboutery when it is convenient is dismaying.
It can serve no humanistic principle to castrate and murder an individual who has done nothing wrong out of expedience for a cause or based on some notion of collective guilt. It is not bourgeois or privileged to sympathize with the athletes who were brutalized nor is it heroic (or even acceptable) to sympathize with their torturers.
