If you want to know just how out of touch the wealthy British people who enjoy torturing and killing foxes for fun are:
We did it lads, we found the least ethical hunters. Jesus England.
This is just good old bullshittery. Everyone decided that talking about Race was Right Out, and so we started talking about Ethnicity instead. And of course this was done to stop precisely these people bigging up their superior Aryan skull proportions. But having adopted a word defined as “the quality or fact of belonging to a population group or subgroup made up of people who share a common cultural background or descent” this just leaves us open to the same old bad faith argumentation. “Aha,” they say. “Inhumanely bothering foxes is a part of my culture, the subgroup of wealthy horse riding assholes! Help, help, I’m being repressed!” And none of it is remotely being done because they’re genuinely thinking that these laws should apply to them, it’s being done to undermine the very concept of this set of laws. A set of laws that was set up to protect people from *them*.
I mean.
The aristocracy genuinely is a group of people who share a common cultural background and, some might say, an extremely common descent.
But I don't think the issue was abandoning race, it was talking about "minority" ethnicities instead of "oppressed" ones (or some synonym of that).
There are also such a thing as privileged ethnic minorities, and the British aristocracy is one, with a long tradition of hunting on horseback going back to when they deprived everyone else of rights to common land so they could use it for sport.
