A Cracker is traditionally a pasty white, fat-assed, Southern Baptist, who longs for the return of segregation. They hate the government. They hate blacks, especially blacks who are more educated than they are which is just about everyone. They hate book learning except where it comes to reading the Bible, even then they hate all that peace and love shit Jesus taught. They love the "eye for an eye" and smiting parts though.
Huckleberry Finn's Pap was a Cracker. So is Wiley Drake.
Oh, yes, this is a wonderful govment, wonderful. Why, looky here. There was a free nigger there from Ohio -- a mulatter, most as white as a white man....They said he was a p'fessor in a college, and could talk all kinds of languages, and knowed everything. And that ain't the wust. They said he could VOTE when he was at home....but when they told me there was a State in this country where they'd let that nigger vote, I drawed out. I says I'll never vote agin. Them's the very words I said; they all heard me; and the country may rot for all me -- I'll never vote agin as long as I live. And to see the cool way of that nigger -- why, he wouldn't a give me the road if I hadn't shoved him out o' the way....They call that a govment that can't sell a free nigger till he's been in the State six months. Here's a govment that calls itself a govment, and lets on to be a govment, and thinks it is a govment, and yet's got to set stock-still for six whole months before it can take a hold of a prowling, thieving, infernal, white-shirted free nigger... ~ 'Pap' Finn, The Adventures of Huckleberry Finn, Chapter 6, by Mark Twain
