Why do Schools get shocked when theres a Swear Word on a Song

Swear Words are just words like we say everyday. I say Swear Words in Arguements because i do and the person i am arguing doesn't go say "Ugh Why Cuss Words we don't say Bad Words here" just treat the Swear Word as a word. And when theres a Swear Word on a song the Teachers get shocked saying we don't say Rude Words guys! And don't forget the song Poker Face by Lady Gaga is not bad at all. If it says "Sex" well its educational to talk about Sex Education. And should be talked about. Like The Word Penis is not bad at all i don't know who says that was a Swear Word because its a Science Word for it. And speaking about Sex Ed Why do Mums and Dads call it a name like Willy and Schlong. No to your kid and i will do it to my kid and be Truthful i will say "That think is called a Penis". Oh this Blog talked about Sex Ed more than the real thing. So why do Teachers have the Audacity if you used a Swear Word to run up and say No No we don't say that or Did you just say a Swear Word oh we are going to Send you for 3486757865347685 Years in Isolation just for saying the word "Fuck". Like its just a word. And a Finger yes a Finger your Middle one is counted Rude. So if we have a middle finger why do we have it then. Am i not allowed to Put the Middle Finger up. They are fine when you have the Index finger, the Ring finger fine by me your Pinky Finger fine by me. your Thumb thats good. Oh the Middle finger No No Very Rude. Oh my gosh my old School i used to go we were not allowed to put your Thumb Down for saying No it was Thumb up for yes and Thumb in the middle for No why not it down its not bad at all.
