A question about race and double standards in Humans

[paulpablo]

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.

I think people need to be educated about the fact that racism is a negative expression of tribalism and nothing else. It served some purpose, in times past, when groups of people needed to protect their scares resources from other groups of people to ensure their own survival. Now o'days, the positive aspects of such tribalistic expression have become all but redundant. As Aractus has indicated, it's impossible to tell one 'race' from another, genetically, and the physiological differences are so few (and easily homogenised within a generation) as to be discounted as an accurate identifier. Race doesn't really exist, racism however is alive and well and must be combatted in every form to ensure equality, justice and fair opportunity for all people.

This still doesn't seem to detract anything from the points I made though, about how could say the same thing for dog breeds as you can for human races.  I don't think anyone would argue that racism is a positive expression.
