I say the right of any sentient agent is that it has a baseline of not deserving to suffer. Here, I like Peter Singer's presentation in "All Animals Are Equal".

I say the right of any sentient agent is that it has a baseline of not deserving to suffer. Here, I like Peter Singer's presentation in "All Animals Are Equal". No one should be made to suffer or harmed in any way without an intervening harm of equal or greater significance to be prevented. If clean food can be gotten for everyone reasonably, then it is impermissible to be greedy or even lazy and not give out the food. If clean food is limited, distribute it such that suffering is minimized. Healthcare wasn't a thing in the time of the Mesopotamians, but now that we have healthcare, it should be provided in the way that minimizes suffering. Land property should not be restricted needlessly, but obviously having some private space is important, so land is still a more exhaustible resource. For acts like sex, suicide, and wanting to be left alone, there is a deep complexity as to informed and unpressured consent. All interaction and therefore anything relevant to rights-talk has a fundamental complexity around understanding another's circumstances and discrimination (as long as all agents are not treated exactly the same, this arises).
