YOUTUBE IS BEING STUPId

Okay, so I wanted to post my music video on youtube. My music video for lullaby that was made for educational purposes and is not meant to infringe on anyone elses work! I hate them for it! gosh I mean it's for educational purposes and I even said that in my copy right dispute and they still have it deleted. I mean it's really free advertisement!!!! There are alot of videos on youtube that have copyrighted stuff in them and their not DELETED!! I mean, i think almost half the videos on youtube have copyright content in them. For instance Twilight fanmade trailers and slideshows. You tube should know that if they delete all of those videos they will loose all of their videos!!! Think about that youtube!!
