Quote:no one who believes otherwise is able to number the "races" they think exist or even categorise them. Is French a 'race'? Is European a 'race'? Is Aryan a 'race'? Well they can't all be - what about French-Canadians are they a 'race'? Which level of categorisation is 'right'?
But I think the point is that there's nothing you've said here that couldn't be said about dogs. All males can breed with every other dog breed so their are mixes, they're basically innumerable since you can get mixed breeds and they can breed with mixed breeds and the breeds become even more mixed.
A lot of dogs are artificially bred unlike humans are though which I'm guessing is why there's more of a clean cut difference between a lot of their breeds, grey hounds will pretty much always be fast, great danes will pretty much always be huge. But there is a bit of that in humans, pygmy tribes are pretty much always short, the fastest runners in the world are usually black people.
All of the examples you listed except for Aryan (I don't know what Aryan is) would be considered nationalities rather than race.
Are you ready for the fire? We are firemen. WE ARE FIREMEN! The heat doesn’t bother us. We live in the heat. We train in the heat. It tells us that we’re ready, we’re at home, we’re where we’re supposed to be. Flames don’t intimidate us. What do we do? We control the flame. We control them. We move the flames where we want to. And then we extinguish them.
Impersonation is treason.
