The real piracy problems lie in peer-to-peer networks. Taking down a site that is used simply for file storage is akin to shutting down a storage center (the ones where you get a mini-garage) because you found out someone was storing a bunch of bootleg CDs and movies in their little garage. I just don't think the government understands the internet, or chooses not to, so they do things like this. Sites like Megaupload delete pirated content, anyway, so it's not like their intent is to store pirated stuff. In real life they wouldn't allow a storage center to search through every belonging you plan to store, yet they wish to do this for the internet. It all just seems so ridiculous.
Again, what is there to convince you of? That US law clearly states copyright infringement and theft are not the same thing? Again, that's a fact. There's no questioning it. That's the reality of situation.
The only reason someone would refer to piracy as theft is either due to 1) ignorance, or 2) as a means of distortion. In the case of the former, they should be more than happy to adjust their language upon being informed of the distinction. In the case of the latter, they are making an emotional appeal. They aren't arguing in good faith, instead using charged hyperbole to make some broader point.
Just like hacker has taken on the connotation as a computer criminal, or mad has taken on the additional meaning of "a lot". When you say someone is pirating something, it just takes on that connotation of thievery. I hack Windows, but that doesn't mean I'm doing anything malicious. Say what you want, but when a culture sets its sights on a new connotation or meaning, it's pretty set in stone. Hacker will never mean what it used to - mad might go out of style, though.
