That seems like a rather extremist point of view to have "a lot of people on here" believe. I imagine it's more that a lot of people on here express that point of view, but if pressed and probed their actual stance would be revealed to be more nuanced and down to Earth.

At least I hope so, because I'm sometimes hopelessly optimistic and even I don't believe the natural state of people is to respect other people's "rights", which are themselves a construct of civilization, not an inherent portion of the human mental state (we often have a hard time defining things like ownership across cultures, much less instinctually understanding someone's right to such).

Edit: meant to end first sentence with "believe", not "express".
