All Right, Look...
1. Anyone who says 'if you don't defend every instance of copyright violation, you lose your copyright' is not allowed to participate in any discussion of copyright. Even if you do agree with the 'every copy is theft' crowd. I mean it. Stop talking right now.
2. Just because I do not agree that every time you make a copy you are stealing food from the mouths of artists or, more explicitly, that every copy is a theft, does not mean that a) I have not done any research on the subject of copyright or b) that I am not entitled to an opinion.
3. Individual instances of copying are not theft no matter how much you wish that they were or really, really want to send your readers, watchers and listeners to jail. It is infringement and is handled in civil court. This does not mean you can't be concerned about infringement or that there is no such thing as criminal infringement, but for crap's sake stop calling every teenager who ever downloaded music a pirate.
4. Being condescending is not the same as being right.
That is all.
