No matter what you say, mom, I will always love him!


Besides.... of course you're right that it's more important to fight for the real thing than to construct a philosophical battle over the meaning of a term. Usually. When you have limited time and resources.

It is my personal experience, though, that the way we speak influences the way we think. Also, the less precise we are in choosing our words, the more likely it is that we run into misunderstandings. (Tell me, is Android a Linux system?)
So choosing our words carefully isn't a bad thing, either. And because in my real life, in my daily conversation, I do have enough time and my resources aren't so limited, no harm's done saying "patents" instead of "intellectual property" and "GNU/Linux" instead of "Linux".
