My objective is to get people to argue precisely why copying is bad. Calling it "stealing", "piracy" and other ugly words is a strawman argument - we all agree stealing (physical items) and piracy (on high seas) is bad, so that would imply that copying is bad, too, since "copying is stealing and piracy". It's not, and additional arguments are needed.
