He coined the concept. Cory linked to the article where he did it. The concept is relevant to the topic of Hodgman’s own self-acknowledged privilege. It has a place in the discussion, even if it makes you uncomfortable on behalf of white cisgender men (a discomfort that apparently isn’t shared by Scalzi, Cory or – briefly putting myself in their company – me, all white cisgender men like Hodgman, AFAIK. Odd that).
The point of Scalzi’s metaphor isn’t to give people the warm fuzzies, but to lay the hard truth on them: if you’re feeling like a loser or are one, it’s not because society is oppressing you because you’re a white straight male; quite the opposite, in fact, so stop blaming the wrong people (who start from a less privileged position) for whatever problems you’re having.
But apparently, even Scalzi framing this concept in a metaphor that will resonate with young white American males, and presenting it in a way that’s less harsh than the blunt version, is going too far in your view (even if you agree with the underlying premise).
To be fair, it’s not only your view. Mainstream American culture quails at the very thought of hurting the delicate feelings of entitled white males by daring to even point out the nature of their privilege. That’s something that has to change.
