Me too, sort of. Though some of the time they threw in something where the offensive caricatures were actually so bad they came off as frightening.
But man, I am no stranger to the embarrassingly okay in the 1960's Asian stereotypes. Seems they really got it bad in the 60's. That Mighty Heroes series I mentioned earlier? Two different Supervillains had incredibly racist Pan-Asian henchmen... and bot with the same voice! These are just painfully embarrassing to watch now.
Actually, I have a funny story. I was at this convention panel where we watched outrageous cartoon moments, and with a huge, long introduction and a blessing from one of the African American audience members, we watched Coal Black and de Sebben Dwarbs.... for all of 2 minutes to dead, stunned silence. Not even an ironic laugh. OUCH!
Now, I am of the kind to say these are awful, but by all means we need to acknowledge they exist for the sake of saying "Dear God, we were freaking horrible back then!" and by denying them, it's almost as bad as them existing in the first place. But I will not actively seek them out and get enjoyment from them. Even the one time I actually find one of these funny (A Sylvester and Tweety cartoon where Sylvester is disguised as a Swedish maid to get Tweety saying "Okay, everybody out unteel I feenish de yob!" gets blown up and turns into a...well... you know...and says "Now Ah Gotta Get Back in da kitch'n! Ah smell Somethin' buuuurrrrrrrrrrnin'!") I feel genuinely horrible about it.
Of course, those uncensored cartoons are best left to DVD collections for older animation fans. The kid friendly reruns that are easily accessible? Edit the heck out of that stuff. They're not ready to know about that stuff yet.
