These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Keep Circulating the Tapes: Unedited versions of the shorts are rare, and the shorts in general have only seen limited DVD release. There was a Droopy DVD set however. Fortunately, there was a Laserdisc set, "The Compleat Tex Avery" released which included ALL of Tex's MGM cartoons (including the two "banned" shorts "Uncle Tom's Cabana" and "Half-Pint Pygmy") uncut. If you look around online, you might just find it for a good price.
Values Dissonance: Many examples mock black people, while "Big Heel-Watha" and "Jerky Turkey" ridicule Native Americans.
The Droopy DVD set even includes a preface acknowledging this, as the shorts are completely uncut.
