No i don't feel this veers to close to politics, because it is impossible to discuss the last ten PDs without going into all this. We need to be careful and it is best to use historic references rather than current issues, and make them generic if possible, but it's an area that demands to be dealt with and fully appropriate here.
It is an issue that most everyone is going to struggle with but I think it is probably one of the first that people will find their way to after battling through the implications of the totally natural and atomistic universe. In such a universe, where there are no gods and no ideal forms, it is literally impossible for there to be "universal rights" apart from what humans create for themselves. There are many aspects of this, and not the least is the multiple meaning of "right" as "something we approve of as correct" vs a "civil right" or a claim that we can make and expect other people to respect. We all want to believe that those exist in some way, but if we rigorously follow the implications of Epicurean physics I think we find that we have to create and uphold those for ourselves.
I ran out of time earlier to link to David Sedley's article "The Ethics of Brutus and Cassius" which does not pay nearly enough attention to this issue as I would prefer, but which makes several comments that the Epicureans were much more willing to take action, as a matter of principle, than were the stoics, to preserve their "rights." There is a lot more to develop on that, but that is why I use the example of Cassius Longinus' discussions with Cicero. Cassius was emphatically and specifically calling upon his Epicurean principles as justification for his fight for justice as he saw it, while Cicero was largely on the sidelines in the battle, and - as Sedley points out - Brutus didn't even bother to ask the true Stoics to participate, since as Sedley says there is no tradition in Stoicism of that kind of action to protect rights. (I am paraphrasing too loosely in interests of time but it is a good article. It contains a short reference linking these ideas back to Epicurus himself:
