The argument I sent to YouTube re: the blocking of my BtVS fanvid is this:
I used small pieces of the visual content from many diverse episodes of this television show, clipped them, edited them, combined them, arranged them, and set them to a previously unrelated piece of music in such a way as to produce a transformative piece of art, which is permitted by law.
Ah well. I don't have a lot of hope, but I figure it's worth standing up and saying what I think about my own rights, rather than just passively feeling bad that someone smacked me down … and giving up immediately on something I want because I believe I can't win. If nothing else, this is probably good for my own personal growth and assertiveness.
So … yay me! Even if I lose, yay me!
