Mininova doesn't host or distribute the content.

Right, so actually storing the illegally-obtained copyrighted content is what you consider wrong.

In other words, you oppose the RIAA going after The Pirate Bay. But by your own argumentation going after, say, a college kid with a terrabyte of fileshared music on his computer is ok, because the material is hosted on his computer.

Could you please confirm that this is what you are saying, or admit that you're in fact engaging in sophistry to justify you stealing content (music), but at the same time defend yourself from others stealing your content (blog entries, technical articles).
