During the days when Toby Keith's "Grandpappy" stalked the Jim Crow South, lynching was an institutional method of terror employed against blacks to maintain white supremacy. According to the Tuskegee Institute, between the years 1882 and 1951, 3,437 African-Americans were lynched in the United States, mostly in the heart of Dixie. Felonious assault and rape (read: corrupting "the flower of white womanhood") were the two most frequent justifications for lynch mob actions.

OMG! Willie Nelson sings this piece of crap song with T.K. I just lost all respect for Willie Nelson.

I am not a fan of Toby Keith nor am I defending lynching, but I think it is a bit of a stretch to make this out to be an ode to lynching. It is immoral to make that stretch and a form of bearing false witness.
I might suggest that it is even racist to make that stretch.
I assume not every person that has ever been hanged nor every gangster was black.
I expect more from you zizzy.

It's not exactly a satire on lynching either.. TK is one of those frustrated individuals for whom our current system of law and order is just too slow and soft. The good ole days in which people took more than just a vicarious pleasure in contemplating the suffering of the wretched, in torture, in cruelty, and blood lust are a source of nostalgia for many, including a certain jingoistic shit kicker who supports the most shameless presidency since Nixon. Fuck 'em.
