I think it means a lot to Donovan not just to be a Mexican skater at Worlds, but a good Mexican skater who earned his spot fair and square. Would those 97 people in Zahra Lahri's position (not 97 Zahras, because there is only one of her) be happy with a spot given out of charity? And (because people who say they're ok with Nathan not being there might just not like his style) skaters like Jason Brown have next to no chance of making Worlds if national diversity quotas limited the dominant federations to 1 spot.
I know the other poster was exaggerating for rhetorical purposes, and I'm not against quotas, but they have to be sensible. I like watching Worlds and JGP because of its diversity compared to JGP/Nationals. But if a quota policy is extremely skewed to favour national diversity, it not only reduces the chance for good (but not top) athletes from bigger federations to shine, but also devalues the merits of athletes from smaller feds who have worked hard to be objectively better than other small fed skaters. As things stand, a range of 1-3 spots per nation plus a minimum TES score is fairly reasonable (even if the means of qualifying spots sometimes isn't). It even favours smaller feds to the point that US/CA/RU-born skaters switch nationalities to get in more easily.
As for the judge quota idea, I just think we should be wary of oversimplifying people's behaviour purely on our own inferences regarding nationality/politics. Are Estonian judges pro- or anti- Russian, given the fact that historical occupation resulted in Russians making up 25% of the population? Do Chinese judges have a bias against Japanese skaters because of historical grievances/current political tensions, or for them due to and cultural/visual commonality? Is a mestizo Mexican judge more likely to favour white skaters depending on the judge's own percentage of Spanish ancestry? I don't dispute that bloc voting can happen, but the world is not black-and-white (pun not intended).
I think that the proposal is interesting precisely because it does not simplify what diverse set of officials could bring to the table. I agree that no one should presume how some would feel, but we’ll never know as long as everyone comes from the same places
I would love to see a few spaces set aside, not many, at worlds or the Olys for skaters who have overcome enormous odds just to set blade on ice. For me, they are “qualified”. And I think my idea has just as much merit as sending the ten “best” (whatever that is) skaters even if they all come from the same country. But that is just an idea, and of course different people will feel different ways.
