The USA is full of prudes and bible bashing fanatics. In years gone by, the later mentioned group set off bombs at abortion centres ... to save lives
So USA being prudish, it's not surprising that years ago, when execs of Nickelodeon realised what was contained within the cartoon Ren & Stimpy, they pulled it from their cable channel. Why, because it was deemed inappropriate for their young audience due to the many crude adult jokes embedded within. Jokes that flew over the heads of the younger audiences but gave something for the older audience, the ones paying the bills to enjoy
So the cancellation only served to peeve off the parents and many were so pissed off that they threatened to cancel their subscriptions unless it was returned.
Luckily execs followed the dollars and oblige their paying customers by returning R&S to the cable channel
Never seen Bluey but if it's like R&S, I should check it out
