I'm just amazed that people decided that 3 relatively random horses (their histories aren't that clear) were the most Horse horses and that any and all horses not related to them are somehow less Horse. Also, seemingly there was an ~80 year span during which other very Horse horses could be defined but that was the limit. That's a link to the article that started it all for me.
I am not a horse person, so this might be obvious to others but it seems absurd to me.
