Sugarfoot Jack, What you're saying is it's OK to have national stereotypes but not racial one. The difference is very blurred as race is divided into many subraces who tend to inhabit different parts of the globe. A French lady is typically different from a Scandanavian lady, both delightful in different ways! A better example is to be found in the Oriental races: the Chinese, the Native North Americans, the Native South Americans and the Innuit are all subraces. There are plenty of cartoon stereotypes of the Irish, the Scots, the Australians, the Japanese and many others, all of which seem to be acceptable.
May I suggest the the problem arises from guilt from the disgraceful way the West has treated (and to some extent still treats) African races.
