"The term characterized farmers having a red neck caused by sunburn from hours working in the fields. A citation from 1893 provides a definition as "poorer inhabitants of the rural districts...men who work in the field, as a matter of course, generally have their skin stained red and burnt by the sun, and especially is this true of the back of their necks".[10]"
AND
"The United Mine Workers of America (UMW) and rival miners' unions appropriated both the term redneck and its literal manifestation, the red bandana, in order to build multiracial unions of white, black, and immigrant miners in the strike-ridden coalfields of northern and central Appalachia between 1912 and 1936. The origin of redneck to mean "a union man" or "a striker" remains uncertain, but according to linguist David W. Maurer, the former definition of the word probably dates at least to the 1910s, if not earlier. The use of redneck to designate "a union member" was especially popular during the 1920s and 1930s in the coal-producing regions of southern West Virginia, eastern Kentucky, and western Pennsylvania, where the word came to be specifically applied to a miner who belonged to a union."
Reading this I'd say if you use the term redneck you are racist (all definitions found used the word "white") and possibly anti manual laborers and anti-union.
Much longer history of racial stereotyping than the term thug. So word police beware!
If we keep this up no one will be allowed to speak, can AMSLAN be racist?
