I suspect we can't even all agree on a definition of unalienable rights.
For me, an unalienable right is the freedom to be or do whatever requires no contribution or participation by another person. Whenever another person is necessary to contribute or participate, it is no longer a right but rather a privilege, a component of social contract, or a coercion.
Right. The key aspect to a right be in 'unalienable' is that it doesn't require another person to actively facilitate. It is a freedom that you'd have even if there were no other people in the world. So, for example, the freedom of speech is unalienable. Even if there were no one else around, you would still be free to express yourself. The freedom to be heard, on the other hand, is not unalienable because it requires that someone else listen.
I don't know whether to blame the conflation around this on historians, or on Jefferson for being too subtle for his own good, but it's really frustrating to see the 'unalienable right' concept get muddied up with dumb debates over whether they are 'god-given' or produced by state mandate. As an atheist, I see neither as literally true. But it seems obvious that 'god-given' was an idiom for 'innate'. I can see why critics of Jefferson's views would have seized on the 'god-given' terminology and strawmanned it. But I'm confounded as to why so many of his supporters buy into the same misconception.
