2Dumb, Corrupt, and Sexually Deviant Vatican: Popetown (2005)
Predictably, the series was attacked by Roman Catholics and quickly banned soon after it premiered in Britain in 2005. However, not only was Popetown deemed too hot for UK or American TV, it's apparently so offensive that it's not even available there on DVD.
3Lesbianism and Slang Terms for Sex: Cow and Chicken - Buffalo Gals (1998)
The episode contained obvious sexual humor, which includes lines like, "Oh! The Buffalo Gals, a motorcycle riding gang that randomly breaks into people's homes and chews on their carpets." Another scandalous moment happens when the Buffalo Gals are playing softball and talking about "pitching" and "catching," which are slang terms for sex.
4Dangerous For Health: Pokemon - Computer Soldier Porygon (1997)

Japan's Fire Defense Agency reported a total of 685 viewers, 310 boys and 375 girls, who were taken to hospitals by ambulances. Although many victims recovered during the ambulance trip, more than 150 of them were admitted to hospitals. Two people remained hospitalized for over 2 weeks. A small portion of the children were diagnosed with photosensitive epilepsy.
5Inciting Pyromania: Beavis and Butthead - Comedians (1993)
MTV pulled the episode, and while it finally returned to the airwaves, its content was seriously edited to remove all the references to pyromania.
In the wake of the Columbine massacre, two episodes that depicted Beavis and Butthead shooting guns were temporarily forbidden in the US, as well.
6Menstruating Virgin Mary: South Park - Bloody Mary (2005)
In the episode, Randy drives drunk and loses his driver's license. He's then ordered to attend Alcoholics Anonymous meetings, where he learns that his alcoholism is a potentially fatal sickness. Meanwhile, the Virgin Mary starts bleeding out of its anus and Randy believes that he can be cured if the statue bleeds on him.
Pope Benedict XVI comes to investigate, and discovers that the blood is actually coming from the statue's vagina. The Pope says that, considering the fact that "chicks bleed out of their vaginas all the time," this is no miracle. Randy, disappointed by this, realizes that God did not heal him and rushes to the bar.
As might be expected, the Catholic League demanded an apology and asked that the episode "be permanently retired" and not made available on DVD. (Source)

12Undertones of Communism and Capitalism: The Powerpuff Girls – See Me, Feel Me, Gnomey (2012)
The Powerpuff Girls are once again fighting all of the villains but they are defeated. Just then, a drop of rain falls into a crack in the ground, and he tells the girls that he can get rid the world of all evil, but to do so the girls must give him their powers.
The girls agree and the gnome casts a spell to end all evil. Townsville is now, seemingly, a peaceful and harmonious utopia, and the townspeople worship this gnome for forming a cult devoted to him.
The Professor convinces the girls that, even though the gnome has provided safety, he has robbed the town of its freewill.

The girls travel to the gnome's headquarters and confront him, returning the world to the way it was.
13Racial Content: Coal Black and de Sebben Dwarfs (1943)
The film is notable for being an all-black parody of the Brothers Grimm fairy tale "Snow White," known to its fans from the popular 1937 Walt Disney animated feature Snow White and the Seven Dwarfs.
The portrayal of the characters, on the other hand, is an example of darky iconography, which was usually accepted in American society at the time.
Because it was produced in America during World War II, there is also anti-Japanese sentiment; the firm "Murder Inc." advertises that it does not charge to kill "Japs."
Only So White escapes the extreme caricature given to the other characters, although she is stereotyped in a different manner. She is depicted as an attractive young woman with a voluptuous figure, which is accentuated by a short skirt and a low-cut, cleavage-revealing blouse.
In Coal Black, So White is the object of sexual desire for every male character in the picture. This draws upon the stereotype of the young attractive black woman as an "exotic" sexual being, a stereotype present in roles that African-American actresses played in American cinema.
Consequently, it has rarely been seen on television and has never been officially released on home video. However, it is often named as one of the best cartoons ever made, in part for its African-American-inspired jazz and swing music.
14Racism and Animal Abuse: Angel Puss (1944)
The cat then disguises itself as its own ghost, painting itself white and donning wings and a halo, and proceeds to "haunt" Sambo by repeatedly sneaking up on him and whispering "boo." Sambo runs away, but the cat rattles a pair of dice, causing Sambo to fall into a trance and sleepwalk back to the cat.
The hauntings continue until Sambo and the cat fall in a pond, washing off the cat's paint. When Sambo realizes that he has been tricked, he kills the cat with a shotgun blast. Immediately afterward, a line of nine ghost cats marches toward Sambo.
