What is a right Ray ? It means something you can't be denide right ?
Nope. The word right is overloaded with lots of definitions, but in the political context a right is an inalienable freedom, a byproduct of free will. And, by convention, when we say something is a "right", we usually mean that it's an inalienable right protected by government.
It really comes down to is a genuine understanding of the concept of inalienable rights, and I've found that to be all too rare - even among those who claim it as a premise. I haven't had much luck, on here at least, explaining the concept to people who didn't already get it. But I'll chase you around that bush if you're game:
The simplest way to describe an inalienable right is that it's a freedom you have if no one else is around. That's why a "right to health care" is nonsense. I suppose you might frame it as a right to take care of your health - but that's not what most people mean. What they mean isn't a freedom at all, it's an obligation on others to give you health care. It's not something you have if no one else is around.
