I'm assuming this is the video about how terrible Disney is? Sigh. The birds in the sky aren't spelling out 'SEX', they're spelling 'SFX' who did some crap for Disney, something like sound I assume.
If it's not that video, then lol ahead, kind sirs.
It doesn't show how any dirty thing can be put into a cartoon, it shows cartoon characters based on male and female genitals which are obscured in the end result. Most artists work from circles and squares when they draw a person, but you don't see it in the end. This movie is about as flaccid as the penises on which the characters are based.
