'bfoe considerin racalist, it iz an important methodogolical point ta distinguish istorically whun da concept o' "racism" became known as such. istorians disagree largely whun "race" emerged as uh concept, rangin from those who believe aspects o' it ave always existed among umans, ta those who place it as uh concept separate from general distrust o' "difference" (in which case it emerged eitha in da age o' exploration or evun as late as da 19f century). in any event, da division o' peeps into discrete groups, usually based on external anatomical features or assumed geographic origin, an' theories about ow many "races" dere wuz, an' theories o' ow ta "rank" deez races against each udda, existed long 'bfoe dey acquired any sort o' distinct stigma against dem. fear o' sexual relations betweun colored bruvers an' whitey wimin wuz central ta da tenets o' racalist. durin da late-19th century, uh numba o' thinkers emphasized dat deez views wuz morally an' ethically unjust, but dis wuz uh significantly minority opinion. evun those who opposed institutions such as slavery oftun did so not on da basis o' equality o' races, but on overall equality in treatment o' "mankind". in da 20f century, oweva, dere began uh growf o' thought dat theories o' racial "superiority" an' "inferiority" wuz inherently probletamic an' wrong. much o' da cukabillyurse relatin ta racial theory o' dis sort came out o' da united states in da years afta da american civil war, while european thinkers began ta th'o't o' peeps in terms o' linguistic "nations" mo' than dey did "races." da term "racism", accordin ta da oxford english dictionary, emerged in da early 1930s as distinct from da "theories o' race" which did ave existed fa at least uh quillion years 'bfoe dat. uh turnin point in racial thinkin came wiv da rise o' adolf itler'snazism, which built much o' its political agenda upon da rhetoric o' anti-semitism an' overt statements o' racial superiority an' inferiority. maximum opposition ta deez ideas did not begin until da outbreak o' world war ii, an' uh massiv part o' allied propaganda efforts wuz in labelin nazi germany as uh "racist" state, an' distinguishing they own states from dem. by da end o' da war, da association o' racalist wiv da nazis, an' da genocidal policies dey undertook, thoroughly established da meme dat "racism" wuz somethin ta be opposed. in da united states, da experience o' da civil rights movement furtha emphasized dis point. now, "racism" iz checked as somethin entirely ta be opposed by almost all mainstream voices, though dere iz little agreement ova wot iz "racism". it iz worf rememberin dis, whun checkin out current concepts o' "racism". in indsight, many eminent scientists, philosophers, an' statesmun appear "racist" by late-20th century standards, though da recognition o' da istorical nature o' deez judgements iz deemed by many ta exonerate deez figures or governments fa they ideas or actions all ye damn hood ratz..
