As for thoughts on the supposed decline of Orcs:
1. In soccer we have a rather crude term to deal over-reliance on statistics: "Possession without penetration is just masterbation." i.e. You can give all the stats you want on possession, passes completed, heat maps, whatever, it doesn't matter if a team isn't doing anything with the ball. In this context, the stats may point to the fact that more and more people are educated, voting Democratic, age etc. But the eye test seems to indicate there isn't any less racism, in fact there seems to be more. For all we know, this country is producing a lot of highly educated, young racists, I mean look at Charlottesville.
2. The Bradley Effect. Simply put, very few people are going to outright, publicly admit they're racist. There are a metric ****ton of closet racists in this country. You want a good idea how to gauge? Start discussing things like Colin Kaepernick or BLM or DACA and you'll find out real quick.
