They are ignoring my argument. My argument is not flawed. We don't accept it in any other context with any other intangible items so I don't understand why it's acceptable here.
Stealing is different to pirating. You can say that both are wrong, but you can't claim that both are the same.
Yes, I can... and I am. They're both wrong because, whatever you call them, they're theft of something. Anything else is just a semantic argument. You're taking something and gaining a benefit from it without compensating the creator for it. We don't accept that in any other context, whether tangible or intangible.
