Yes, these cartoons are politically incorrect but they are still historic and part of the culture they came from. I enjoy watching these types of programs. Sadly, the political correctness has run amok in the non-propaganda cartoons also these days. The "violence" in the old Bugs Bunny and Daffy Duck cartoons has been horrendously censored for TV. Watching them now is painful when you see how blatant the editing is.
If I ever see a DVD with the unedited/uncensored originals in it I'm snapping it up in a hurry. I find it incredibly ironic that the morons who censor the hell out of an old Daffy Duck cartoon don't seem to have a problem with South Park or Family Guy which are shown during prime time these days.
As mentioned, signs of the culture we live in I guess.
