We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
There is nothing new there in the age-old nature-nurture game. Does it really need saying that people who are more closely related likely have more traits in common? "Race" and "ethnicity" are just words for common ancestry, like "distant cousins." Early humans spread around the earth, and bred with others in their own neighborhoods just like Darwin's finches. Naturally, differences happened but not to the extent of new species, but enough so that people recognize their cousins.
