That's overly simplistic, sort of like saying there's no difference between a Mercedes and a Yugo. Both are cars, aren't they?
I've tried explaining to you that copyright re: music and literature are, by law and by fact, not the same. Until you realize this, there's no point in arguing with you. We'll just agree to disagree.
I'm sorry I seem not to be getting my point through. Let me try to simplify it. Both issues involve the protection of income by the party holding the copyright, and an effort by others to deny or bypass that income through a violation of the copyright.
To use your analogy, lets compare the theft of a Mercedes and that of a Yugo. Both are grand theft auto, aren't they?
Now if your point is that, compared to Beavis here downloading Metallica albums for his personal use, your indiscretion is being "less of a thief", you might have an argument, though I dont think it would work in a court of law for the Yugo thief (he might however succeed with an insanity plea).
