They used to say that about black people...
Oh, for chrissakes, it's true of black people! This isn't bigotry, it's genetics.
Many of the genes that make up "blackness" or "orientalness" tend to be dominant. Many of the genes that make up "Europeanness" are recessive. This means that white people come in a bewildering variety: redheads, blondes, brunettes, curly haired, wavy haired, straight-haired, very tall, tall, average, short, very short, giant noses, tiny noses, blue eyes, green eyes, brown eyes, giant noses, tiny noses, white skinned, olive skinned. Basically, our genes are wussy. Anybody can push them over. That, and we outbreed a lot.
There's a good deal more variation in American blacks than African ones, because we've been trading genes for so long. How many of the above characteristics do you expect to find in African blacks? Han Chinese? And what the hell is wrong with saying it?
Terror of being called a racist has run through this country like a plague of stupid.
