I'm 17 and youtube is banning me from watching music videos with the word "****" in them?

I tried watching "Cee Lo Green - **** You" and apparently, I'm too young to hear people sing the word "f�ck"? I mean are they serious? What the hell is up with that? This might seem like a rant, but I actually want to know. I've heard that damn word ever since I started watching american movies when I was 7, as I imagine most other teenagers have that are on youtube, so what argument could they possibly have to support this censoring?
