My point was that what is seen as 'merit' is a function of a whole bunch of other factors, which means it isn't somehow a racists discussion stopping thing to point out that Asian men have higher levels of 'merit' (when merit is defined in the way I understood it to be in the post I was responding to). My point in using 'privilege' is to say that the idea of 'merit' overlaps with 'privilege' in the ways I described, and that the people the OP might thing of as wanting to 'stop' the discussion, do, in fact, have this discussion a lot, though they'd use 'privilege' instead to mean those things, because that is the term of art.
You seem to have a problem with a word. Call it 'probabilistic causes of non-equal representation', then. Point out there are many such causes, and some of them are hardly things we could easily change (there are very few people with very low IQ in top tech jobs, so higher IQ is a 'privilege'). Your reaction to the word, rather than the point, seems rather ideological.
Tautology is not a synonym for synonym. And the equation you accuse me of making is a strawman, my point was to unpack merit, not to define privilege. I'm sorry if it was unclear.
